Abstract

The indiscriminate use of pesticides in Malaysian agriculture poses serious risks to both human health and groundwater quality.This study aims to evaluate the extent of pesticide contamination in Malaysian groundwater, identify its major sources, and examine current mitigation efforts. The primary routes of contamination include direct application, soil leaching, and surface runoff, with over twenty pesticide compounds listed as priority hazardous substances, commonly linked to oil palm, rice, and vegetable farming. Residential and industrial activities also contribute to the pollutant load. Due to their long environmental persistence, pesticides threaten aquatic ecosystems through bioaccumulation and biomagnification and increase the risk of severe health issues, including neurological disorders, reproductive problems, and cancer. Regulatory controls such as exposure limits and monitoring programs have been implemented to manage these risks. This review concludes that while regulatory mechanisms exist, more robust and proactive approaches are needed to mitigate groundwater contamination. Future efforts should focus on expanding the adoption of sustainable farming practices, strengthening groundwater monitoring, and enhancing regulatory enforcement to ensure long-term environmental and public health protection.

Abstract

Some life history aspects including the reproductive characteristics and population dynamics of Senegalese tongue sole (Cynoglossus Senegalensis, Kaup, 1858), in the coastal waters of Ghana, were studied between August 2018 and July 2019. The length data of 606 specimens from the coastal waters of the Greater Accra region of Ghana was analyzed for size structure, growth pattern, condition factor, sex ratio and length at first maturity. The mean length varied significantly (p -value < 0 .001) with sex (31.3 ± 0.4 cm in males, 34.3 ± 0.4 cm in females). Condition factor (K) did not vary significantly (p -value = 0.054) with sex (i.e. 0.466 ± 0.002 in males, 0.476 ± 0.004 in females). The gonadosomatic index (GSI) varied significantly p -value < 0 .001) with sex (2.29 ± 0.30 in males), (3.94 ± 0.25 in females) and spawning peaks in April and July. Five maturity stages were recorded for both sexes with the size at first maturity for females and males estimated at 44.1 cm and 38.3 cm, respectively. In conclusion, the assessed fish species is likely to experience recruitment failure in the future, if appropriate management measures are not in place. Reduction in fishing efforts ad establishment of closed season is highly recommended.Keywords: Cynoglossus senegalensis; Ghana; Growth; Fisheries management; Life history.
