Soil is an important environmental matrix that directly or indirectly supports the life of all creatures. Despite being the ultimate sink for all contaminants, it has been neglected for a long time, resulting in poor soil quality. Due to the contamination of various toxic polycyclic aromatic compounds (PAHs) in soil, it diverts the quality of soil and impacts the soil ecosystem. Henceforth, it is necessary to identify the ecologically sustainable treatment alternatives for contaminated site cleanup. Biological treatment of PAHs contaminated soil is emerging as a promising and sustainable treatment options because they are safe, cost effective and eco-friendly treatment solutions. When it comes to pollutant degradation, microorganisms are known for their enzyme-catalyzed catabolic activity, w hich can be advantageous in the decomposition of PAHs. There are various microbes which are extensively used for the removal of PAHs, in which This review paper compiled a various recent in-situ and ex-situ bioremediation techniques used for the degradation and remediation of PAHs in agricultural soil.

Accurate information on land use/land cover dynamics is needed for the selection and implementation of land use programs to meet the rising demands of basic human requirements and wellbeing. Land use land cover transition analysis is a rigorous approach that helps to understand physical and human involvement in the natural environment as well as sustainable development. Thus, the study aims to predict the land use/land cover of Ludhiana, Punjab state, for the year 2033 using the MOLUSCE plugin. Classified land use/land cover maps for the years 2009, 2015, and 2020 were prepared in the Google Earth Engine platform. The prediction model used these prepared classified maps along with four generated spatial variables maps i.e. slope, elevation, distance from road, and distance from water maps. According to the study, the built-up area might grow by 85.79 sq. km between 2020 and 2033. Forecasted reductions in vegetation, bare soil, and water class cover could total 23,91, 49,02, and 12,87 square kilometers, respectively. The res

The study presents a revenue-based land information system integrated with the crop information. In this study, Sentinel-2 and Planet imagery have been used for crop classification using supervised classification. The accuracy attained from the Planet image was 90.67% and 82% for Sentinel 2, respectively. The study finds that the rice crop was grown a significant portion in the study area. The result shows the Murabba and Khasra based information of the existing Land use and Land cover information and Planet data provides better adjustment with the cadastral data. This integration includes essential information for identifying crops at the Khasra level and revenue base estimation of crop yield for the particular land parcel.

The application of agrochemicals into the environmental matrix has sluggishly degraded the quality of their original form. Pesticide consumption in the agricultural sector has been used for the quantity production of crops however, now considered as a culprit for the quality crops. Lands that once provided ample crops of good quality are now facing a case of severe damage impacting their crop quality. The prime need is to reclaim these contaminated matrices. For the same, an eco-friendly approach should be adopted. One such approach is the application of biochar for pesticide sorption. Biochar is a carbon-rich, stabilized product acquired when biomass undergoes pyrolysis at 200-650˚C. It is known for sequestration ability and mitigation of environmental contaminants. Its properties (surface area, pore size, ash contents, and functional groups) determine the potential for sorption. Biochar when modified is most effective for the sorption mechanism. For instance, rice straw biochar when treated with phosphoric acid (T-RSBC) showed stronger adsorption capacity for sorption in waste water effluent. Corn straw when doped with phosphorus functional groups was highly effective for adsorption of triazine pesticide from water. Other biochar that could remove pesticides are corn cob and corn starch. Activated coconut shell biochar showed the highest adsorption capacity for diazinon removal from water than other modified coconut shell biochar. Plant biochar (pine needle, oak wood, corn stover) having a high content of lignin have better properties such as large surface areas (112-642 m g ) and macropores (0.06- 1.90 cm g ) that increase the sorption capacity of pesticides in soils than animal and cellulose-based biochar. This review paper aims to evaluate the role of biochar in the sorption of pesticides from soil and water.
农药在环境基质中的应用已经缓慢地降低了其原始形态的质量。农业部门的农药消费一直用于作物的数量生产，但现在被认为是优质作物的罪魁祸首。曾经提供大量优质作物的土地现在正面临严重损害影响其作物质量的情况。当务之急是回收这些被污染的矩阵。同样，应该采取生态友好的方式。其中一种方法是应用生物炭吸附农药。生物炭是一种富含碳的稳定产物，当生物质在200-650˚C下进行热解时获得。它以封存和减轻环境污染物的能力而闻名。它的性质(表面积、孔径、灰分含量和官能团)决定了吸附的潜力。改性后的生物炭吸附机理最有效。如稻秆生物炭经磷酸处理后(T-RSBC)对废水出水的吸附能力较强。掺磷官能团的玉米秸秆对水中三嗪类农药有较好的吸附效果。其他可以去除农药的生物炭是玉米芯和玉米淀粉。活性椰壳生物炭对水中二嗪农的吸附能力高于其他改性椰壳生物炭。具有高木质素含量的植物生物炭(松针、橡木、玉米秸秆)具有比动物和纤维素基生物炭更好的特性，如大表面积(112-642 m g)和大孔隙(0.06- 1.90 cm g)，从而增加了土壤中农药的吸收能力。本文综述了生物炭在土壤和水中对农药的吸附作用。

This state is the second largest state in India both in terms of population and geographical area (11.23 Cr. and 3.08 lakh sq. km. respectively). The State is highly urbanized with 42 % people residing in urban areas. The state has 255 statutory towns and 279 census towns, it generates the maximum sewage throughout Maharashtra in India is around 13% with 8,143 MLD as against treatment of 5,160.36 MLD through sewage treatment plants (STPs) at least 3,000 million liters of sewage and industrial effluents flow into rivers, water bodies or percolate into the ground every day.

Land use in developing nations is shifting as a result of rapid urbanisation. The ecosystem is being harmed by the unplanned, urban development of cities. Utilizing data from Landsat, the present research examined the spatiotemporal urban growth in Jalandhar City and its impact on variations in land surface temperature (LST). The results indicate that urban regions have increased while urban green spaces have shrunk (UGS). UGS and LST have been found to be inversely correlated. Where there was a low percentage of urban areas and a high percentage of accessible green spaces, it was observed that the LST decreased. The link between spectral variability and changes in vegetation growth rate was studied using the NDVI (Normalized Difference Vegetation Index). It works on tracking the growth of green vegetation and spotting variations in the amount of greenery. Where NDVI value was low, the scatter plots indicate higher surface temperatures. The dense urban regions with little available vegetation cover were linked to the low NDVI number and the NDVI is negative in the urban area of Jalandhar. High NDVI values indicate regions with dense vegetation and low surface temperatures. The research findings of present study could be applied to urban administration, planning, management and research projects.

The greater wax moth Galleria mellonella L. is a serious destructive pest of honeybee colonies in the beekeeping industry all over the world. The larvae feed on almost all of the honeybee products and have the ability to completely destroy the bee colony, especially the weakened ones. The toxicity and biochemical effect of garden cress, Lepidium sativum seeds methanolic extract as natural product against greater wax moth was evaluated under laboratory conditions. The defatted seeds (250g) of garden cress were refluxed in 500 ml methanol, filtered and then dried using a rotary evaporator. Results revealed that the toxic effect of the garden cress extract against 5 instar larvae of G. mellonella was 1.15%, (LC50) after 24h. which induced more histopathological alterations on cuticle layers, fat bodies and muscle. A significant reduction in protein content, as well as high significant inhibition in α, β esterase and phenol oxidase activities were also recorded. On other hand, the extract induced an elevation in total lipid content and acid phosphatase activity. Furthermore, apoptotic DNA fragmentation was occurred at concentrations of 3, 2 and 1%. GC-MS analysis illustrated the toxic effect of methanol extract of L. sativum seeds is related to a high ratio of phenolic, flavonoid and fatty acids constituents.
