The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
Mysuru: Sri Jayachamarajendra College of Engineering (SJCE) under its third Global Initiative of Academic Networks (GIAN) programme will organize a 10-day course on 'fate and transport of contaminants in the environment' on its premises from Monday. The course tutor is professor Rajesh Seth, department of civil and environmental engineering, University …
The aim of the present study is to investigate LC50 values in three seasons of TBTO on L. marginalis. The active substance TBT is highly toxic damaging to non target species. The bivalves have been bioindicators to determine aquatic pollution status. The adverse effect of Tributyltin oxide has been studied …
Diabetes and obesity are major threats to public health in the US and abroad. Understanding the role chemicals in our environment play in the development of these conditions is an emerging issue in environmental health, although identifying and prioritizing chemicals for testing beyond those already implicated in the literature is …
A method for the determination of 200 pesticides and pesticide metabolites in honeybee samples has been developed and validated. Almost 98% of compounds included in this method are approved to use within European Union, as active substances of plant protection products or veterinary medicinal products used by beekeepers to control …
European governments have banned the use of three common neonicotinoid pesticides due to insufficiently identified risks to bees. This policy decision is controversial given the absence of clear consistency between toxicity assessments of those substances in the laboratory and in the field. Although laboratory trials report deleterious effects in honeybees …
The study monitored the toxicity of environmentally relevant concentration of pesticides and metals in zebra fish Danio rerio. Zebra fish were exposed to environmentally relevant concentration of pesticides and metals for a period of 14 days. The individual and the combined toxicity of pesticides and metals were evaluated. The pesticides …
Children’s toys are made of artificial material often softened by phthalates. These are synthetic compounds added to PVC as plasticizers for the purpose of improving its elasticity and flexibility. Phthalates can endanger the health of children exposed to their effect by inducing reproductive, hormonal and developmental disorders. The goal of …
Growing food in unconventional systems such as those using irrigation with domestic wastewater and the use of potentially toxic waste has generated resistance from producers and consumers. Here, we evaluate the possible physical and biochemical damage to Swiss mice fed for 13 weeks with corn produced in soil containing tannery …
Several studies suggest that exposure to organophosphate insecticides (OP) during pregnancy impairs neurodevelopment in children. The researchers evaluated associations between biomarkers of prenatal and postnatal OP exposure and cognitive function of 6-year-olds in a French longitudinal birth cohort. Original Source
Atmosphere, earth and water compose the environment. The presence of heavy metals in the environment has grown because of their large employment in some industrial and agricultural activities. Although these metals are terrestrial products, they flow into the sea through effluents and sewage or are directly discharged from industries placed …
Trihalomethanes (THMs) and haloacetic acids (HAAs) are regulated disinfection by-products (DBPs); their joint reproductive toxicity in drinking water is unknown. The researchers aimed to evaluate a drinking water mixture of the four regulated THMs and five regulated HAAs in a multigenerational reproductive toxicity bioassay.

Pesticidal stress is very common factor today in human health and animal health. Most of the world s population depends upon fish food. Fishes can serve as bioindicators of environmental pollution since they are directly exposed to chemicals resulting from agricultural production via surface run off or in directly through …
Phthalates are used as plasticizers in soft polyvinyl chloride (PVC) and in a large number of consumer products. Due to reported health risks, di-isononyl phthalate (DiNP) has been introduced as a replacement for diethyl hexyl phthalate (DEHP) in soft PVC. This raises concerns since animal data suggest that DiNP may …
Mitochondrial dysfunction has been implicated in the pathogenesis of a variety of disorders including cancer, diabetes, and neurodegenerative and cardiovascular diseases. Understanding whether different environmental chemicals and drug-like molecules impact mitochondrial function represents an initial step in predicting exposure-related toxicity and defining a possible role for such compounds in the …
This paper brings together over 250 published and unpublished studies on the environmental properties, fate, and toxicity of the four major, high-volume surfactant classes and relevant feedstocks. The surfactants and feedstocks covered include alcohol sulfate or alcohol sulfate (AS), alcohol ethoxysulfate (AES), linear alkylbenzene sulfonate (LAS), alcohol ethoxylate (AE), and …
Mancozeb and its main metabolite ethylene thiourea (ETU) may alter thyroid function; thyroid hormones are essential for fetal brain development. In Costa Rica, mancozeb is aerially sprayed at large-scale banana plantations on a weekly basis. The objectives of the study was to (1) evaluate urinary ETU concentrations in pregnant women …
In June, 2014, 20 experts from nine countries met at the International Agency for Research on Cancer (IARC; Lyon, France) to assess the carcinogenicity of perfluorooctanoic acid (PFOA), tetrafluoroethylene (TFE), dichloromethane (DCM), 1,2-dichloropropane (1,2-DCP), and 1,3-propane sultone (1,3-PS). These assessments will be published as volume 110 of the IARC Monographs.
The groundwater in nearly 31 districts in Uttar Pradesh has been found to have a strong arsenic contamination which exposes the people to slow and consistent toxin. A technical report titled Arsenic toxicity in ground water of Uttar Pradesh shows that the concentration of arsenic in groundwater exceeds the Bureau …
Children today are sicker than they were a generation ago. The past few decades have seen a rapid rise in the consumption of synthetic pesticides. The world now uses about 2.3 million tonnes of pesticides every year, which is 50 times more than in 1950. The widespread use of pesticides …
