All US states, and many countries around the world, have waterways with environmental health advisories intended to protect individuals from harmful chemicals in fish, yet little is known about how informal science educators, even those who engage anglers along waterways, incorporate advisory information into their educational activities. This study, grounded in environmental health literacy, investigated the practices, knowledge, and beliefs of 24 informal educators housed in varied agencies and organizations in a southeastern US state. Participants described a range of educational activities and identified organizational constraints on their education about fish consumption advisories, which varied by organization type. Their knowledge of relevant environmental health concepts was incomplete, and they described health and teaching beliefs consistent with limited focus on advisory education. Local government and nonprofit educators were well positioned to educate anglers about advisories, due to their freedom to design and deliver instruction and their regular contact with anglers. Educators in wildlife agencies had more contact with anglers and were identified as potential conduits given their interactions, but organizational constraints (such as educators’ ability to choose content/pedagogy and conflicting missions of agencies) would need to be addressed.

Food waste can be converted to a useful product such as biochar as a way of recycling waste to retain nutrients in the soil, which in turn contributes to carbon sequestration and offset some greenhouse gas emissions in the struggle to achieve carbon neutrality. Mixed food waste-derived biochars (FWB1–300°C, FWB2–450°C and FWB3–600°C) were pyrolysed at 300°C, 450°C and 600°C, respectively, using an electric kiln. Tests for physiochemical parameters and germination tests were performed. It was realized that at 300°C biochars produced had high nitrogen, organic matter, bulk density, biochar yield, and longer root lengths. The results indicate that municipal food waste biochars produced at three temperatures were suitable for use as fertilizer. However, biochar produced at a moderately lower temperature is favourable for agriculture purposes, FWB1–300°C and FWB2–450°C obtained moderate pH and ash levels and so are less toxic to the growth of plants.

Human decisions and modes of organization can be analyzed according to their rationale, which can be based on hierarchies, markets, or networks. This classification is known as governance modes. This article addresses municipal solid waste (MSW) governance inside and outside protected areas based on the Sepultura Biosphere Reserve (REBISE) case in Chiapas, Mexico. We conducted semi-structured interviews and a content analysis of laws and municipal regulations to identify the stakeholders and institutions that operate at community and municipal levels. Our research is a first effort to analyze the modes of MSW governance and offers a spatially explicit classification to reveal the spatial differences in how MSW is governed. The populations close to the capital city and the main roads have a multiplicity of mechanisms and modes of MSW governance, which contrasts with distant communities located within the REBISE. This work illustrates the gaps where municipal authorities are unable to fulfill their obligations and the potential of market and collaborative mechanisms. Characterizing governance modes through spatially explicit thematic maps reveals the interactions between stakeholders and formal and informal institutions, which could contribute to territorial planning toward more effective MSW governance.

Recent studies have focused on the processing of biowaste to obtain added value and to reduce organic waste in the general stream. This study investigated the synthesis of magnesium oxide (MgO) from magnesium-rich Cucurbita pepo (pumpkin) seeds for a precursor solution as a reducing agent via an eco-friendly method for the first time. The pumpkin seeds were ashed at 550°C for 6 h and subjected to acid-leaching. Mg(OH)2 was then precipitated using an aqueous solution of 2.0 M NaOH. The Mg(OH)2 was then calcined at 550°C for 4 h to obtain MgO. Physicochemical properties (i.e. proximate analysis, elemental composition, electrical conductivity (EC), pH) and selected heavy metals (i.e. Pb, Fe, As, Cd, Cr, Hg, Cu, and Ni) analyses were conducted on the seed samples and as-synthesized MgO. X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier-transform infrared (FTIR), citric acid test (CAT), and acid neutralization capacity (ANC) tests were techniques used to characterize the synthesized MgO. The results revealed the percentage yield of the MgO to be 23%. The pH of the as-synthesized MgO was recorded as 10.63. XRF studies showed that MgO made up 75.1% of the total weight synthesized. XRD results showed the presence of crystalline cubic structures of MgO. FTIR results showed a peak at 584 cm−1 which confirmed the formation of MgO. The produced MgO was highly reactive, with a CAT time of 2 s. The ANC of the MgO was high at 22.77 mol+/kg. Also, metal concentrations such as Fe, Cu, Cd, Ni, Pb, Hg, As, and Cr in MgO were below the WHO stipulated limits of 350, 36, 0.8, 35, 85, 0.03, 40, and 100, respectively. This implies its suitability for soil remediation purposes. Results indicate that the as-synthesized MgO from Cucurbita pepo (C. pepo) seeds could be used for several applications due to its high alkalinity, reactivity, and fast CAT time.

Risk and crisis communication (R&CC) are crucial elements of managing vulnerability to big threats. This paper aims to explore the trends and contributions of scientific publications to R&CC about South America. Through the examination of 330 papers listed in the Web of Science database, the current study conducted a thorough overview between 1998 (oldest study) and 2021 (cut-off date) of bibliometric networks (keyword co-occurrence map, co-authorship maps, and author co-citation map) and multivariate statistical models (principal component analysis, compositional linear model). We address main communication factors, links between communication factors and countries, main academic cooperation networks, determinants of publication trends, and most cited authors. 28 R&CC factors were mapped and their relative importance to various hazards was examined. Most of these factors were intended to strengthen the communication system and increase risk knowledge of vulnerable people. Chile, Colombia, and Ecuador were mostly focused on strengthening R&CC. Brazil and Argentina were best represented with health and exposure to pollutants communication. Publications on R&CC are determined by the level of wealth, tourist arrivals, and the number of people affected by disasters. The compositional analysis revealed that the behavior of publications determinants could have opposite tendencies depending on the threats’ multidimensionality. To the best of our knowledge, this is the first R&CC study on South America to use CoDA in a bibliometric analysis.
风险和危机沟通(R&CC)是管理重大威胁脆弱性的关键要素。本文旨在探讨南美洲科学出版物的发展趋势及其对R&CC的贡献。本研究通过对Web of Science数据库中收录的330篇论文的分析，对1998年(最早研究日期)至2021年(截止日期)的文献计量学网络(关键词共现图、合著图、作者共被引图)和多元统计模型(主成分分析、构成线性模型)进行了全面的综述。我们讨论了主要的传播因素、传播因素与国家之间的联系、主要的学术合作网络、出版趋势的决定因素以及被引用最多的作者。绘制了28个R&CC因子的分布图，并考察了它们对各种危害的相对重要性。这些因素大多是为了加强沟通系统和增加弱势群体的风险知识。智利、哥伦比亚、厄瓜多尔等国家主要致力于加强R&CC。巴西和阿根廷在健康和接触污染物的交流方面最具代表性。关于R&CC的出版物是由财富水平、游客数量和受灾害影响的人数决定的。成分分析表明，根据威胁的多维度，出版物决定因素的行为可能具有相反的趋势。据我们所知，这是R&CC首次在文献计量学分析中使用CoDA对南美洲进行研究。
