Effects of 2,4-dichlorophenol on non-specific immunity, histopathological lesions, and redox balance in African Catfish, (Burchell, 1822).

The toxic effects of 2, 4-dichlorophenol (2, 4-DCP) on aquatic organisms are well-established; however, the details regarding the mechanisms underlying the toxicity, especially immunotoxicity are poorly understood. Consequently, the aim of this study was to investigate the histopathologic, oxidative stress and immunotoxic effects attributed to exposure to sublethal concentrations of 2,4-DCP in the African catfish, . Juvenile were exposed to 0.

Tissue Distributions and Toxic Effects of Hexavalent Chromium in Laboratory-Exposed Periwinkle ( Linnaeus).

The increased use of hexavalent chromium (Cr) in various industrial applications has contributed to its elevated levels in the environment, especially the aquatic environment. Thus, there is the potential for accumulation of Cr in the tissues of aquatic organisms and consequent toxic effects. The toxic effects of Cr in aquatic organisms have been widely reported; however, little is known about the patterns of tissue accumulation of Cr and its toxicity in aquatic mollusks.

Occurrence of trace elements in print paper products: Non-carcinogenic risk assessment through dermal exposure.

Over time, the risk assessment of dermal exposure to pollutants in print paper products has received considerable attention. Most studies have focused on organic pollutants, especially bisphenol A (BPA). However, little is known about the levels of trace elements in print paper products, despite the knowledge that these elements are components of printing inks and toners.

Tissue Accumulation, Cytotoxicity, Oxidative Stress, and Immunotoxicity in African Catfish, Clarias gariepinus Exposed to Sublethal Concentrations of Hexavalent Chromium.

Hexavalent chromium (Cr) is one of the stable oxidation states of chromium that has been reported to elicit various toxic effects in aquatic organisms. However, the mechanisms of Cr toxicity are still poorly understood. Thus, the present study investigated the tissue accumulation, cytotoxic, oxidative stress, and immunotoxic effects of Cr in juvenile Clarias gariepinus.

Health implications of pesticides application among cocoa farmers in Idanre local government area, Southwest Nigeria.

Pesticides are routinely applied by cocoa farmers to enhance cocoa production, which is threatened by pest infestations and diseases. However, the undesired health implications of pesticide applications on the farmers are yet to be fully elucidated especially among cocoa farmers in Idanre despite being the hub of cocoa production in Southwestern Nigeria. This study assessed the extent of pesticide use by cocoa farmers in the study area and determined the effects of exposure on their health using haematological and biochemical parameters as indices.
