Article Synopsis
- Jazan Industrial Economic City (JIEC) is a hub for various heavy industries in Saudi Arabia, including petroleum and water desalination, which produce significant amounts of industrial wastewater containing toxic substances.
- The study focuses on isolating 32 fungal strains from this wastewater that can tolerate multiple heavy metals and have efficient bioremediation capabilities for pollutants like crude oil and polycyclic aromatic hydrocarbons.
- Among these fungi, isolate JAZ-20 exhibited outstanding bioremoval efficiency, achieving up to 100% removal of several harmful pollutants and demonstrating low levels of antibiotic resistance within the mycobiome.
Assessment of chlorinated pesticide exposure to white-rumped vulture Gyps bengalensis in India.

Populations of the critically endangered white-rumped vulture (WRV) Gyps bengalensis have declined drastically due to the use of diclofenac for veterinary purposes in Indian subcontinent. Thirty-two dead WRVs collected from three states, namely Gujarat, Assam and Tamil Nadu in India between 2011 and 2014 were investigated to understand the role of diclofenac in the death, and the results were published. Furthermore, since organochlorine pesticides have been linked to long-term impact on populations in many species of birds across the globe, available tissues of 21 WRVs were tested also for six organochlorine pesticides (DDT, HCH, endosulfan, heptachlor, dieldrin and dicofol) and chlorpyrifos.

The potential negative impacts of organochlorine pesticides on the environment and human health continue to receive attention. In order to study the spatial distribution characteristics of organochlorine pesticides in the inland alpine region, researchers collected soil and water samples in the Huangshui River Basin of the Qinghai-Tibetan Plateau and tested them for organochlorine pesticide residues represented by dichlorodiphenyltrichloroethane (DDT) and hexachlorohexane (HCH). The study identified the sources of OCPs by component analysis.

Pesticides are toxic and could negatively impact humans and the ecosystem. The Kitchener Drain is among the longest drains in Egypt and carries a wide range of wastewater from the agriculture sector, which contains pesticides and may pollute the ecosystem. Thus, water quality, human health risk, and pesticide accumulation in African catfish and Nile tilapia from the Kitchener Drain-Egypt.

Article Synopsis
- Environmental exposure to dicofol (DCF), a common organochlorine pesticide, poses potential health risks due to its toxicity, with limited understanding of the effects of oral exposure on mice.
- In a study, mice were given varying doses of DCF to observe metabolic changes via H NMR-based metabolomics, targeting liver metabolism and gut microbiota.
- Results showed that DCF exposure led to liver injury, disrupted fatty acid metabolism, and caused changes in gut bacteria and their metabolites, highlighting its harmful effects on both liver and gut health.
