Professor Elvis Asare-Bediako, the Vice-Chancellor of the University of Energy and Natural Resources (UENR) has cautioned vegetable farmers against the use of contaminated wastewater in growing crops because of adverse health implications for human beings.

He explained some wastewater contained heavy metals and other micro-organisms.

“If used such water is used to water crops, especially vegetables that are eaten raw, they go directly into the human system,” he cautioned

He advised farmers to dig boreholes to serve as a source of water for watering crops because that is better, compared to using contaminated water.

Prof Asare-Bediako gave the caution in an interview with the Ghana News Agency after a public lecture on the theme, ”Prescription for Better Environment and Prevention of Spread of Non-Communicable Diseases: The Perspective of the Geoscientist,” at Sunyani, as part of activities marking the 10th-anniversary celebration of the UENR this year.

He said: ’The type of water used in watering some of the vegetables is worrying, and that’s where we contract food poisoning before heavy metal contamination also contributes to the other health implications.’

He noted it was difficult to identify vegetables on the market grown with contaminated water that contained heavy metals, saying that made it more dangerous to the health of the consumer.

Prof Asare-Bediako also spoke against the ways vegetables were preserved at the markets before being sold to consumers, saying “they become even more contaminated at the markets,”

He advised the public to always purchase vegetables from known sources.

Prof. Emmanuel Arhin, a geoscientist of the Department of Geographic Science, School of Geo-Sciences, UENR, who gave the lecture on the theme said lack of essential elements and excesses of toxic elements that humans were exposed to lead to health problems such as non-communicable diseases.

According to him, ‘research suggests that identifying the geo-availability of elements holds the key to control the prevention of many environmental health diseases.”
