A few days ago, the Guangdong Provincial Quality Supervision Bureau conducted the 2013 provincial periodic supervision and inspection. On the 25th, they announced that the quality check covered 15 product categories, including artificial boards, waterproof coatings, **kitchen furniture**, bathroom furniture, and other home improvement materials. The results showed a serious issue with substandard products, and many well-known brands were found to contain harmful substances, some of which are linked to cancer risks.
Formaldehyde has long been a major concern for merchants in the artificial board industry and is also a key focus during quality inspections. In this round of checks, out of 322 batches of wood-based panel products from 199 companies in cities like Guangzhou, Shenzhen, and Foshan, 38 batches failed the test. Among them, 12 had excessive formaldehyde levels. Several well-known brands, such as "Daizhou Color Butterfly," "Peng Bang Wood," "Pine Tree," and "KONE," were also included in the list. For instance, two products under the "Daizhou Color Butterfly" brand were found to have high formaldehyde emissions.
In addition to formaldehyde, a new chemical—anthracene—was also detected in this inspection. Like formaldehyde, anthracene is harmful to human health. According to the official announcement, the "Ouqi" brand 911 polyurethane waterproof coating (5L/set) produced by Foshan Ouqi Coating Co., Ltd., and the 911 two-component polyurethane waterproof coating (20kg/barrel) from Sanshui Junfu Building Waterproof Material Co., Ltd., were found to have unqualified levels of anthracene, naphthalene, and solid content.
Anthracene is a crystalline chemical substance. While pure anthracene is non-toxic, industrial-grade anthracene can cause skin and mucous membrane irritation. High concentrations may lead to facial discomfort, and severe cases could result in toxic encephalopathy or liver damage.
Experts from the Quality Supervision Bureau advised consumers to request third-party authoritative test reports when purchasing wood-based panels. Products with formaldehyde emission levels meeting the E1 standard (≤9mg/100g using the perforation method, ≤1.5mg/L using the dryer method) can be used directly indoors. Those reaching the E2 level (≤30mg/100g using the perforation method, ≤5.0mg/L using the dryer method) must be treated before indoor use.
When buying waterproof coatings, it's recommended to avoid products with poor packaging, irregular containers, or unclear labels. Opting for well-known brands from reputable manufacturers is safer. (Editor: Peter)
