df Up to 157 polluting firms in the southern province of Dong Nai have spent more than 1.5 trillion VND (68.1 million USD) on dealing with environmental pollution since 2009, according to the provincial Department of the Environment and Natural Resources.
As many as 143 of them have been removed from the list of polluters, said Head of the provincial Environmental Protection Agency Vo Niem Tuong.
The remaining are building wastewater and exhaust gas treatment systems.
The department still conducts regular supervision and collects samples for pollution testing to prevent possible relapses.
Relevant agencies also launched campaigns to raise business awareness of the importance of environmental protection as well as to encourage the adoption of eco-friendly technologies.-VNA
