In a developing country context, this study explores environmental awareness, stakeholder influence strategies, and pollution prevention roles among 11 local, civil society groups (e.g., environmental nongovernmental organizations [NGOs] is one grouping; media and press is another grouping). A theoretical framework that builds on the social movement literature and is more inclusive of a developing country context is offered. In essence, awareness-raising is also considered a stakeholder influence strategy. Based on surveys conducted in Chittagong, Bangladesh, the results of this empirical study show that 10 of the 11 groups were environmentally aware; however, only the environmental NGOs were willing to influence the other groups. The environmental NGOs were actively raising awareness, but they were not directly influencing firms or the federal government on pollution prevention. These findings challenge the generalization of current stakeholder influence theory to a developing country context and raise concerns about the capacity of local civil society to encourage pollution prevention.

“…Phytoplankton, being both a primary producer and important component of aquatic ecosystems, can create fresh organic matter, carbon dioxide (CO 2 ), and energy for the usage of other trophic levels (Deines, Bunnell, & Rogers, 2015;Deng, Zhang, Li, Shi, & Zhang, 2017;Lakshmi et al, 2014), thus playing a fundamental role in aquatic food chains (Wu, He, Cai, Zhang, & Chen, 2014;Cao, Chu, Du, Hou, & Wang, 2016), material circulation, energy flow, and information transmission (Cai, Zhu, & Li, 2013). Phytoplankton community characteristics and primary productivity (PP), which reflect the ecological and nutritional status of water, are all important indicators for the estimation of the productive capacity and the evaluation of eutrophication, trophic level, and the health status of water environments (Islam, Alfasane, & Khondker, 2013;Patil & Chavan, 2010).…”

Phytoplankton community characteristics and associative primary productivity, which reflect the ecological and nutritional status of water, are sensitive to environmental change. Particularly, nutrient inputs have a significant effect on phytoplankton growth and development as well as the biogeochemical cycle of watersheds. We investigated the phytoplankton community and nutrient status downstream from the Gan River into Poyang Lake. On a catchment scale, the phytoplankton communities and associative primary productivity from these two water bodies differed. The Poyang Lake phytoplankton community is composed of seven phyla of algae, whereas the Gan River is composed of six, the dominant phyla of phytoplankton being Bacillariophyta and Cryptophyta in Poyang Lake and Gan River, respectively. Phytoplankton abundance and primary productivity were significantly higher in Poyang Lake. Lower nitrogen (N) and phosphorous (P) concentrations and higher carbon (C) and silicon (Si) concentrations significantly affected the phytoplankton communities and primary productivity distribution in the entire Poyang Lake Basin. In this regard, we found a significant correlation between the phytoplankton community of the Gan River and P and N, whereas N and Si primarily regulated the phytoplankton community structure of Poyang Lake. Moreover, we found a significant correlation between DTN, Si/P, DIC/P, and primary productivity in the Gan River, whereas NH4+ jointly controlled primary productivity in Poyang Lake. Furthermore, the Margalef Richness Index (0.84–2.41) can be indicative of the environmental water quality status; and we determined that the most area of Poyang Lake and Gan River both were P restriction and moderately polluted, whereas the entrance of the Gan River into Poyang Lake was seriously polluted, which confirms that the Gan River is a main and crucial source of Poyang Lake pollution. Nanjishan Nature Reserve was already slightly eutrophic due to the high nutrient content and a large number of algae in the south‐east of Poyang Lake, but the Gan River had good river fluidity, so some areas of the Gan River were oligotrophic.

Leishmaniasis is considered one of the different neglected tropical diseases by the World Health Organization. Over the past few decades to tackle leishmaniasis, effective and novel drugs have progressed. But few are expensive some other medication shows poor effects and few drugs with long treatment lead to cause resistance. But it is very important to start a better medication against leishmania so researchers came to the front of the utilization of natural products which are considered a better option. Finding active compounds in medicinal plants is another alternative to currently accessible medications. Materials and methods: This study examined and reported the far more potential natural products used to treat disease caused by Leishmania spp. Leishmaniasis, plant metabolites, in vivo, in vitro, and treatment against leishmaniasis have been used as search terms in the Google Scholar, PubMed, and Science Direct databases, and only papers published between 2015 and 2021 have been chosen for further analysis. Results: The use of novel natural compounds with leishmanicidal action as well as the leishmanicidal activity of natural compounds against promastigote, axenic, and intracellular amastigote forms were included in roughly 20 research papers that were reviewed.Conclusion: Due to their capacity to selectively target parasites without harming host cell viability, herbal plants are a possible source of new anti-leishmanial medication. Future leishmaniasis treatments will draw on the isolated compounds as a source, completing those already offered in clinics.
