Chinese Drywall 2: Corrosion Link

A second report from the Consumer Product Safety Commission (CPSC) on Chinese drywall has found “a strong association† between homes with the problem drywall and the levels of hydrogen sulfide and metal corrosion in those homes. However, the findings on possible health effects are less definitive. “While drywall-related corrosion is clearly evident, long term safety effects are still under investigation,† CPSC said. The study of 51 homes also found elevated levels of formaldehyde and hydrogen sulfide, both of which are known irritants at sufficiently high levels. “While hydrogen sulfide and formaldehyde levels detected in homes containing the problem drywall were at concentrations below irritant levels, it is possible that additive or synergistic effects of these and other compounds in the subject homes could cause irritant effects,† CPSC noted. Over at the Huffington Post, Brian Skoloff cites the Formaldehyde Council, a trade group, saying there is no scientific evidence to support the theory that formaldehyde and hydrogen sulfide can combine to cause adverse health effects. The investigation continues. To-date CPSC has received about 2,091 reports in 32 states, the District of Columbia, and Puerto Rico, from residents who believe their health symptoms or metal corrosion in their homes are related to the presence of Chinese drywall.
