This was announced by Baskut Tuncak, the U.N. special rapporteur on human rights and hazardous substances and wastes, Censor.NET reports referring to RFE/RL.
"Battles are now being fought in cities, close to industrial centers, with factories increasingly becoming at risk of being hit: the consequences for anyone living close-by would be severe," he said.
On Feb. 24, Tuncak said, a shell hit a building housing more than 7,000 kg of chlorine gas.
No storage container was damaged in the shelling, according to Tuncak.
But he warned that if one single 900-kilogram container had been broken, it could have killed everyone within a 200-meter radius and could have resulted in severe health damage for those living as far as 2.4 kilometers around the damaged facility.
The Office for the Coordination of Humanitarian Affairs (OCHA) has also voiced concern about potential impact to the health of residents. According to information cited in the press release, OCHA and humanitarian partners have called for demilitarizing the areas adjacent to civilian infrastructure and for essential safety equipment to be stored at facilities out of the reach of the government.
