Arsenic and di-(2-ethylhexyl) phthalate (DEHP) are environmentally ubiquitous and epidemiologically important toxic agents that millions of people are currently exposed to, worldwide. Although the adverse impact due to exposure to either arsenic or DEHP are documented, the toxicological effects of co-exposure to these agents are largely unknown. In this study, exposure to these chemicals was investigated for their... Read more.

Due to insufficient clean water resources, wastewater is largely used for irrigation of vegetables and fruits in many developing countries like Nigeria. As a result of this, vegetables in spite of providing nutrients also accumulate toxic metals and causes health risks. In the present study, the levels of heavy metals (lead (Pb), cadnium (Cd), iron (Fe), zinc (Zn), and copper (Cu)), were analyzed using Atomic Absorption... Read more.

Lack of consensus in published works regarding cypermethrin's ability to produce teratogenic and embyotoxic effects has led to postulations. The aim of this study was to evaluate the teratogenic and embryotoxic effects of cypermethrin in 5% vegetable oil using albino rats. Acute toxicity study of cypermethrin was evaluated using Probit analysis method. Percentage mortality was calculated and LD50 was... Read more.

Gas flaring is a recognized polluting agent in the environment, affecting all forms of life. The gases and particulate matters (dust, mist and fog) follow the same diffusive pathway with carbon IV oxide into the plant leaf, where they react with enzymes, hormones, and other biochemical molecules, resulting in the deformation of organelles with adverse consequences. In this study, foliar photomicrography analysis of five... Read more.

The indiscriminate use of pesticides in developing countries has impacted negatively on the environment and public health. Despite that informal households in Uganda carry a high pest burden, the safe use and disposal of pesticides is poorly studied. We determined the prevalence and pesticide use practices among the informal households in Mulago, a suburb of Kampala city. A cross-sectional survey was conducted among... Read more.

India is an agricultural country; animal husbandry has always been associated with agriculture. People still thrive upon animal products such as milk, meat and manure intensely for their essentialities. India has a huge cattle population and most of them graze in areas close to forests and their fringes competing for their pastoral needs with other wild animals. This then leads to human-wildlife conflicts, which tends... Read more.
