The study was carried out in Egor local government area, Dumpsite in Ovia North-East local government area of Edo state. The study areas are located between latitudes of 6°27'27.8''N to 6°27'44.6''N and longitudes of 5°35'58.7″E to 5°36'16.8''E in Egor local government area and the dumpsite is located with a latitude of 6°22´1.2''N to 6°27´51.3″N and longitudes of 5°36'42.3''E to 5°36´2.1″E in Ovia North-East local government area. A total of five (5) water samples were collected from an existing borehole at different locations within the study area. Physiochemical test, Major anion and cation concentration was determined using Atomic Absorption Spectrophotometer (AAS). Microbiological Parameters for all the water samples was also determined. The following are the physiochemical parameters, major cations and anions that was analysed from all the water samples collected: pH, EC, TDS, Na+, Ca+, Mg2+, Cl-, NO3- , HNO3- , HNO3- , SO42- , Cr2-, Cd-, Ni-, and Pb2+ and the Microbiological parameter analysed for all the water samples are Coliform and E. Coli. The Microbiological parameter analysed for are Coliform and E. Coli as shown in Table 1. The results reveals that the study areas have average value of pH (4.89) which is below the WHO (2011) and NSQW (2007) standard permissible limit of 6.5-8.5 and this indicates that the water is slightly acidic probably due to the presence of decayed organic matter in high amounts and mineral acids produced during hydrolysis. The average values of E.C (121.86μS/cm), TDS (46.52mg/l), Na+ (1.48mg/l), Cl- (53.85mg/l), NO3- (1.17mg/l), HNO3- (0.39mg/l), SO42- (0.12mg/l), Cr2- (0.031), and Ni- (0.0074) conforms with the WHO (2011) and NSQW (2007) standard for drinking water expect some physiochemical parameters : Ca2+, Mg2+ Cd-, Pb2+, E.Coli and Coliform which has average values (4.49mg/l, 3.10mg/l, 0.027mg/l, 0.016mg/l, 1.36 X 103 (cfu/100mL)and 1.06 X 103 (cfu/mL) which do not conform with the WHO (2011) and NSQW (2007) for drinking water because of many factors and anthropogenic activities on the environment which contaminated the groundwater of the study areas. The results analysed from the three-study area reveals that the physiochemical parameters and microbiological parameters show similar trend. The water sample collected in the premises of University of Benin is more acidic compare to other water samples from the other locations. This probably due to the presence of decayed organic matter in high amounts and mineral acids produced during hydrolysis.
该研究是在埃戈尔地方政府区、埃户州东北部奥维亚地方政府区的垃圾场进行的。研究区位于Egor地方政府区域北纬6°27′27.8”至北纬6°27′44.6”,经度5°35′58.7″E至5°36′16.8”E之间,垃圾场位于Ovia东北地方政府区域北纬6°22′1.2”N至6°27′51.3″N,经度5°36′42.3”E至5°36′2.1″E之间。从研究区域内不同位置的现有钻孔中共采集了五(5)个水样。理化试验,采用原子吸收分光光度法(AAS)测定主要阴离子和阳离子浓度。测定了所有水样的微生物学参数。所有水样的理化参数、主要阳离子和阴离子分析如下:pH、EC、TDS、Na+、Ca+、Mg2+、Cl-、NO3-、HNO3-、HNO3-、SO42-、Cr2-、Cd-、Ni-、Pb2+。所有水样的微生物参数分析为大肠菌群和大肠杆菌。所分析的微生物参数为大肠菌群和大肠杆菌,见表1。结果表明,研究区域的平均pH值为4.89,低于WHO(2011)和NSQW(2007) 6.5-8.5的标准允许限值,表明水体呈微酸性,可能是由于大量腐烂的有机物和水解过程中产生的无机酸的存在。除部分理化参数外,E.C (121.86μS/cm)、TDS (46.52mg/l)、Na+ (1.48mg/l)、Cl- (53.85mg/l)、NO3- (1.17mg/l)、HNO3- (0.39mg/l)、SO42- (0.12mg/l)、Cr2-(0.031)、Ni-(0.0074)的平均值符合WHO(2011)和NSQW(2007)饮用水标准。研究区地下水中Ca2+、Mg2+、Cd-、Pb2+、E.Coli和大肠菌群的平均值分别为4.49mg/l、3.10mg/l、0.027mg/l、0.016mg/l、1.36 X 103 (cfu/100mL)和1.06 X 103 (cfu/mL),不符合WHO(2011)和NSQW(2007)的饮用水标准。三个研究区的理化参数和微生物参数分析结果显示出相似的趋势。与其他地点的其他水样相比,在贝宁大学馆舍收集的水样酸性更强。这可能是由于存在大量腐烂的有机物和水解过程中产生的无机酸。

The association between systemic lupus erythematosus (SLE) and thrombotic thrombocytopenic purpura (TTP) is a described but rare situation and usually occurs in cases with intense lupus activity and renal impairment. It may occur in less than 2% of patients with systemic lupus erythematosus. We present below a case of SLE that abruptly debuts an episode of PTT de aggressive course, treated in an interdisciplinary way with plasma exchanges and immunosuppressants and immunomodulators.

This study investigated the economic and environmental impact of poultry production in Ilorin, Kwara State. Primary data were used and a sample of 120 poultry farmers through a multistage sampling technique was drawn from the study. The data collected were analysed using descriptive statistics, gross margin analysis, OLS regression model and Likert-type scale. The results show that the enterprise incurred an average total variable cost of N135,450.0 and total revenue within the period was estimated to be N192,323.80 which was mainly generated from the sales of poultry birds. The gross margin was found to be N56,873.8 with N0.4199 can be obtained with a unit increase in the poultry production capacity. Thus, the broiler production is a profitable venture in the study area. The empirical finding based on the regression result indicate that, cost of labour, cost of chicks and marital status had positive coefficient and statistically significant in influencing the total revenue level. It means that any increase in their value will increase the revenue level. The result of vaccine/medication administered against diseases revealed that most of the poultry farmers uses Lasota vaccine (88%) against Newcastle disease, a combination of amprolium and coccimapro (27%) each for Coccidiosis, pox off (88%) for fowl pox disease, Gumboro vaccine (65%) for IBD gumboro and their sources of getting the medication/vaccines are majorly from Aromokeye agro vet and One step pharmacy. The analysis shows that among the various ways of waste management, the farmers uses the waste more for fertilizer (28%) followed by selling them (23%) while only (21%) of the farmers burn the waste (especially the dead birds) so as to prevent further spread of diseases on the farm. The empirical findings based on the environmental impact of poultry production reveals that waste generation is the major negative environmental impact of poultry production in the study area. Offensive odour also associated with poor waste management is ranked 2nd, diseases transmission, air pollution and water pollution are among the environmental impact of poultry production in the study area. Poor management system is perceived to be the major constraint, lack of security and government support ranked 2nd is seen as a problem.
本研究调查了Kwara州Ilorin家禽生产的经济和环境影响。使用了原始数据,并通过多阶段抽样技术从研究中抽取了120名家禽养殖户的样本。采用描述性统计、毛利率分析、OLS回归模型和likert型量表对收集到的数据进行分析。结果显示,该企业的平均总可变成本为N135,450.0,期间的总收入估计为N192,323.80,主要来自禽类销售。毛利率为N56,873.8,每增加一个单位的家禽生产能力可获得N0.4199。因此,肉鸡生产在研究地区是一项有利可图的投资。基于回归结果的实证发现,劳动力成本、雏鸡成本和婚姻状况对总收入水平的影响均为正系数,且具有统计学意义。这意味着任何价值的增加都会增加收入水平。对疾病进行疫苗/药物治疗的结果显示,大多数家禽养殖户使用Lasota疫苗(88%)预防新城疫,使用amprolium和coccimapro联合疫苗(27%)预防球虫病,使用水痘灭剂(88%)治疗禽痘病,使用Gumboro疫苗(65%)治疗IBD Gumboro,他们的药物/疫苗来源主要来自Aromokeye agro vet和One step pharmacy。分析表明,在各种废物管理方式中,农民将废物用于肥料(28%),其次是出售(23%),而只有(21%)的农民将废物(特别是死鸟)焚烧,以防止疾病在农场进一步传播。基于家禽生产环境影响的实证研究结果表明,废物产生是研究区家禽生产的主要负面环境影响。恶臭也与废物管理不善有关,排在第二位,疾病传播、空气污染和水污染是研究地区家禽生产对环境的影响。糟糕的管理系统被认为是主要的制约因素,缺乏安全和政府支持排在第二位被视为一个问题。

Agricultural and agro-industrial activities generate large quantities of waste which are harmful to the environment. This waste, rich in organic matter, can be recycled and transformed by biotechnological processes which constitute a solution of choice for remedying pollution problems. The aim of this study is the treatment of the organic fraction of waste by anaerobic digestion, which consists of degradation in the absence of oxygen of the organic matter into a mixture of methane (CH4) and carbon dioxide (CO2) called biogas. For this we have chosen the following samples (manure ; manure mixed in bananas, oranges, lemons, potatoes and tomatoes ; manure mixed in breads, zucchinis, carrots, cucumbers and strawberry). We used a biogas plants based on simple tools. Among these samples, the T container (manure) the most productive mixture of biogas and the T (manure) and F2 mixture (manure + breads + zucchinis + carrots + cucumbers + strawberry) degraded faster than the F1 manure + mixture (bananas, oranges, lemons, potatoes and tomatoes). The micromycetes that these samples contain are Penicillium italicum, Penicillium digitatum, Rhizopus sp, Mucor, Aspergillus sp, Cladosporium. Micromycetes give good biogas yield. The genus Aspergillus accelerates the degradation of organic matter. Anaerobic digestion not only prevents pollution, but also produces energy, compost and replenishes nutrients. Anaerobic digestion can turn a waste problem into a source of wealth. This technology is becoming essential in the process of reducing waste and producing biogas, a source of renewable energy.
农业和涉农工业活动产生大量对环境有害的废物。这种富含有机物质的废物可以通过生物技术过程加以回收和转化,这是补救污染问题的一种选择解决办法。这项研究的目的是通过厌氧消化处理废物的有机部分,它包括在缺氧的情况下将有机物降解成甲烷(CH4)和二氧化碳(CO2)的混合物,称为沼气。为此,我们选择了以下样品(肥料;香蕉、橙子、柠檬、土豆和西红柿中混合了肥料;肥料混合在面包、西葫芦、胡萝卜、黄瓜和草莓中)。我们使用了基于简单工具的沼气厂。在这些样品中,T容器(粪便)(最高产的沼气混合物)和T(粪便)和F2混合物(粪便+面包+西葫芦+胡萝卜+黄瓜+草莓)的降解速度快于F1粪便+混合物(香蕉、橙子、柠檬、土豆和西红柿)。这些样品中含有的微真菌有意大利青霉、指状青霉、根霉、毛霉、曲霉、枝孢霉。微菌产生良好的沼气产量。曲霉属加速有机物的降解。厌氧消化不仅可以防止污染,还可以产生能量、堆肥和补充营养。厌氧消化可以把废物问题变成财富的来源。这项技术在减少废物和生产可再生能源沼气的过程中变得至关重要。

Duffy, Lk
The health effects caused by pollution released into the environment is a continual problem facing the survival of sensitive species on our planet. Even though legislation regulates energy industries in many countries, the continual release of pollutants, such as heavy metal accumulation and persistent organic pollutants, are impacting climate change which will lead to social and cultural changes. These changes will continue to negatively impact both regional and global environments. There is a need for a combination of a One Health ecosystem interdisciplinary approach with an Environmental Justice ethic in order to maintain our ecosystems and the communities which they support at optimal health levels globally.
释放到环境中的污染造成的健康影响是我们这个星球上敏感物种生存面临的一个持续问题。尽管许多国家的能源工业受到立法管制,但污染物的不断释放,如重金属积累和持久性有机污染物,正在影响气候变化,从而导致社会和文化变化。这些变化将继续对区域和全球环境产生负面影响。有必要将“一个健康”生态系统跨学科方法与环境正义伦理相结合,以便在全球范围内将我们的生态系统及其所支持的社区维持在最佳健康水平。

Degradation and solubilisation of plant organic wastes using P. pulmonarius is a recycling technology that could be explored and adopted in developing countries. The test substrates; saw dust (SD), sugarcane bagasse (SB) and maize stalk (MS) and in combination (SD+MS, SD+SB, SB+MS, SD+MS+SB) contained polysaccharides that were degraded by P. pulmonarius. The hemicelluloses, cellulose and lignin contents of the agro-wastes were significantly (P<0.05) degraded by the fungus to varying degrees. The loss of hemicelluloses content of the substrates ranged from 24.98% with MS substrate to 44.02% with SB substrate, cellulose content from 16.13% with SD substrate to 32.79% with SB substrate and lignin content from 8.07 % with SB substrate to 31.25% with MS substrate indicating that the fungus can not only efficiently degrade agricultural wastes and grow at a wide range of substrates but also of importance in biodegradation and bioremediation of a wide range of wastes and pollutants.

Nature Conservation in Communities of Rural India through Perspective of UN SDGs 从联合国可持续发展目标的角度看印度农村社区的自然保护
Pub Date : 2023-01-18 DOI: 10.58489/2836-3590/007
The global community is divided on economic status. The conditions of the poor communities are critical, especially in developing and underdeveloped nations. Most of these nations belong to the Asian, African, and South American continents. The nations from these continents owe rich natural heritage and cultural diversity. The eco-cultural ethos embedded in the indigenous customs and traditions of these nations has global relevance in the modern age of information. It is fact that the solution to any environmental challenge exists in the cultural roots of the nation. India is one of such nations which inhabit diverse eco-culture. The purpose of this paper is to understand the natural heritage of rural India and the local conservation practices prevalent in the rural communities to achieve the targets of UN SDGs. Undoubtedly, nature conservation and environment protection involve social dimensions connected to the local ecological setup. The eco-centric approach of the Indian culture lies in the concepts of ‘Vasudhaiv Kutubkam’ (Earth is one family), ‘Aranya Sanskriti’ (Forest Culture), and the ‘Prakriti Purush’ (Natural Human) which are deeply embedded in the traditions and the customs of the Indian society. Based on traditional conservation practices, the community manages the local natural heritage. The diversity of customs and traditions results in the vividness of the conservation practices. Thus, the socio-ecological systems could be used for site-specific conservation programs and policies.
国际社会在经济地位上存在分歧。贫困社区的状况是危急的,特别是在发展中国家和不发达国家。这些国家大多属于亚洲、非洲和南美大陆。这些大陆上的国家拥有丰富的自然遗产和文化多样性。这些国家的土著习俗和传统中蕴含的生态文化精神在现代信息时代具有全球意义。事实上,任何环境挑战的解决方案都存在于民族的文化根源中。印度就是这样一个拥有多样化生态文化的国家之一。本文的目的是了解印度农村的自然遗产和农村社区普遍存在的当地保护实践,以实现联合国可持续发展目标。毫无疑问,自然保护和环境保护涉及到与当地生态环境相关的社会维度。印度文化以生态为中心的方法在于“Vasudhaiv Kutubkam”(地球是一个家庭)、“Aranya Sanskriti”(森林文化)和“Prakriti Purush”(自然人类)的概念,这些概念深深植根于印度社会的传统和习俗中。基于传统的保护实践,社区管理着当地的自然遗产。习俗和传统的多样性导致了保护实践的生动性。因此,社会生态系统可以用于特定地点的保护计划和政策。

Maximum industry uses groundwater which is consumed for cooling, product treatment and cleaning, processing, boiler make-up, etc. To assess the industrial water quality, the groundwater samples were collected from pre-monsoon and post-monsoon periods and investigated some selected water parameters. The lower values of pH, Cl-, SO42-, CO32, and NO3-; and the higher levels of total dissolved solids, water hardness, total alkalinity, Ca2+, HCO3-, copper, and iron were the dominant chemical characteristics in the study area. This water chemistry proved that the circulated and feed cooling water have a less corrosive tendency, but it produced scale in equipment. Approximately 100% of the samples were less suitable for the wood, food, paper, and sugar industries, and about 85% of the samples were unsuitable for the canned fruit and polymer industries. The storability and corrosion potential of water were assessed using several indexes based on analyzed water parameters. The results revealed that the bicarbonate regulating index values of the samples indicated a moderate to strong corrosive nature, whereas there was a less scale-forming tendency for boiler use. The study observed the need to continually monitor the corrosion potentiality in industrial systems and conduct laboratory analysis to maintain water quality standards including pH, alkalinity, Ca2+, and HCO3- to control corrosion and scale generation.
大多数工业使用地下水,用于冷却,产品处理和清洗,加工,锅炉维修等。为了评价工业水质,在季风前和季风后采集了地下水样本,并对一些选定的水参数进行了调查。pH、Cl-、SO42-、CO32、NO3-值较低;总溶解固形物、水硬度、总碱度、Ca2+、HCO3-、铜和铁是研究区的主要化学特征。水化学实验证明,循环水和给料冷却水具有较小的腐蚀倾向,但在设备中产生水垢。大约100%的样品不太适合木材、食品、纸张和制糖行业,大约85%的样品不适合罐装水果和聚合物行业。在分析水参数的基础上,采用多项指标评价了水的储存性和腐蚀电位。结果表明,样品的碳酸氢盐调节指标值显示出中等至强腐蚀性,而锅炉使用的结垢倾向较小。该研究发现,需要持续监测工业系统中的腐蚀潜力,并进行实验室分析,以保持水质标准,包括pH值、碱度、Ca2+和HCO3-,以控制腐蚀和结垢。

An Evaluation of the Levels of Fe, Ag, Mn and Co in Fish, Sediments and Water from Adada River 阿达达河鱼类、沉积物和水中铁、银、锰、钴含量的评价
Pub Date : 2023-01-13 DOI: 10.58489/2836-3590/005
This study was carried out to determine the concentration of Fe, Co, Mn and Ag in the fish, sediment and water from Adada River. The result thus obtained showed the hierarchal arrangement of the heavy metal from the locations. Akpugo Fish (Fe>Mn>Ag>Co, Sediments Fe>Mn>Co>Ag and Water Co>Ag>Mn=Fe, Aku Fish Fe>Mn>Co>Ag. Sediments Fe>Mn>Co>Ag and Water Ag>Co>Mn=Fe, Lejja Fish Fe>Mn>Co>Ag. In the sediments Fe>Mn>Co>Ag and water Ag>Co>Mn=Fe. The result indicates that these heavy metals studied were all detected in sediments, fish and water except that there was complete absence of Mn and Fe in all water collected from the three sites. This suggests pollution of the river which may pose a threat to the aquatic organism.

The study was undertaken within the Satna and Rewa districts of Madhya Pradesh. the planning one-shot-case study under the ex-post-facto approach was used for this research study. The districts and therefore the tahsils both were selected randomly. Two blocks from each district and 6 grama panchayat with 8 members from each block selected randomly. Thus, a complete of 192-gram panchayat members from 24 villages were selected for the study. Data was collected by personally interviewing the respondents with the assistance of a specially designed and pretested schedule. Statistical methods like mean, variance, coefficient of correlation, multiple regressions were used for the analysis of knowledge. it had been concluded that the bulk of gram panchayat members had a medium role perception of the functioning of Gram panchayat. it had been found that the majority of the gram panchayat members had a medium perception of their role within the administration, agricultural functions, health care functions, administrative functions, welfare functions, public work functions defense and vigilance functions, and other functions. While educational and cultural functions perceived is within the high category. it's observed that the independent variables viz., age, caste, landholding, annual income, socio-economic status, social participation, achievement motivation, mass media exposure, cosmopoliteness, linkage with development agencies, and knowledge were positively and significantly related with role perception. multiple correlation analysis the role perception of gram Panchayat members was found significantly related with age, annual income, and linkage with development agency
这项研究是在中央邦的Satna和Rewa地区进行的。本研究采用了事后法下的规划一次性案例研究。这些地区以及相应的tahsils都是随机选择的。从每个区选出两个街区和6个村委会,每个街区随机选出8名成员。因此,来自24个村庄的192克村务委员会成员被选为研究对象。数据的收集是通过亲自采访受访者与一个特别设计和预先测试的时间表的帮助。运用均值、方差、相关系数、多元回归等统计方法对知识进行分析。得出的结论是,大多数克拉姆村务委员会成员对克拉姆村务委员会的职能只有中等作用的认识。调查发现,大多数克村委会成员对其在行政、农业职能、保健职能、行政职能、福利职能、公共工作职能、国防和警戒职能以及其他职能中的作用有中等程度的认识。而教育和文化功能的感知则属于高范畴。研究发现,年龄、种姓、土地占有、年收入、社会经济地位、社会参与、成就动机、大众媒体曝光、国际化程度、与发展机构的联系、知识等自变量与角色感知呈显著正相关。多元相关分析发现,村委会成员的角色感知与年龄、年收入、与发展机构的关联显著相关
