Abstract
In the process of operation of inland ports and wharves, there are dust, noise, solid waste and wastewater discharges ... these wastes cause environmental impacts. Items that cause unpleasant odors such as sulfur, petroleum, fertilizer, and animal feed are volatile goods, which are unpleasant to those around the area. In addition, noise in the port area has a rather large negative intensity caused by boats operating and repairing at ports; due to excavators, due to cranes, due to goods conveying belt that cause noise pollution causing occupational deafness for people operating in that area. Emissions from transportation vehicles, construction machinery operating on ports and under rivers can pollute the air environment, increase greenhouse gas emissions ... causing climate change. The wharves and yards are usually not covered by roofs, or materials to shield them, goods are kept outside the yard, usually bulk goods, construction materials such as sand, stone, coal, ore, wood, fertilizer ... not shielded when there is wind to sweep sand dust, stone dust, coal, ores far away, affecting the health of people living in the surrounding area (causing respiratory diseases: pneumonia and bronchitis chronic). When it rains, rainwater will wash these goods down the water causing pollution of the water environment. The quality of inland waterway vehicles in Vietnam is often not high, many vehicles are too old, backward, fuel combustion efficiency is low and there is no exhaust treatment system ... so many toxic gases were emitted such as SO2, CO2, CO, NO2, CxHy. It can be said that this is the source of pollution for the air environment, increasing the greenhouse gas effect of the inland waterway industry.
