1.3m cubic meters of factory waste let into Dhaka rivers every day
About 1.3 million cubic meters of industrial waste water and harmful chemical enter the four Dhaka rivers daily causing serious environmental and ecological hazards, according to the analysis of the Action Aid Bangladesh.
The analysis paper titled Environmental Impact of Bangladesh Fashion Industry shows that such practices especially entering harmful chemical in the rivers raises a number of environmental concerns.
Talking to the Daily Observer Farah Kabir, Country Director of Action Aid Bangladesh, said, all aspects of the industry such as spinning, weaving, knitting, wet processing and readymade garment manufacturing pollute air, water and soil.
Most of the factories are located nearby the rivers, posing serious threat to the environment as they release untreated solid and liquid waste into canals and rivers, she added. "Huge quantity of wastes with hazardous chemicals are being dumped into the rivers every day, affecting severely water bodies, the marine ecosystem, reducing fish population and resulting in unsuitable land for cultivation," she added.
Referring to the health issue, many experts said many rice paddies now inundated with toxic wastewater are also causing serious bad impact on health.
They noted that the dumped poisonous wastes kill the micro organism of the soil and also the soil become contaminated with heavy metal like lead, mercury, chromium.
"Factory wastes destroy soil's moisture and gradually turn the soil infertile. Later the contaminated soil mixed up with different food cycles and finally people become affected through this food cycle," said Paval Partha, a researcher of ecology-biodiversity and conservation.
Engineer Abdus Sobhan, General Secretary of Poribesh Bachao Andolon, said most industries do not have waste treatment facilities. "In most cases, industries having ETPs do not operate the plants. So our rivers everyday receive some 62 types of toxic chemicals, including cyanide, chromium, mercury, chlorine, and different types of acid, zinc, nickel, alkali, lead and cadmium, are dumped into the main rivers of Dhaka city like the Buriganga, the Turag, the Balu, the Shitalakkhya, the Dhaleshwari and the Bangshi ," he added.
