The impact of surfaces on indoor air chemistry following cooking and cleaning† Cooking and cleaning are common sources of indoor air pollutants, including volatile organic compounds (VOCs). The chemical fate of VOCs indoors is determined by both gas-phase and multi-phase chemistry, and can result in the formation of potentially hazardous secondary pollutants.

Does green mean clean? Volatile organic emissions from regular versus green cleaning products† Cleaning products emit a range of volatile organic compounds (VOCs), including some which are hazardous or can undergo chemical transformations to generate harmful secondary pollutants. In recent years, “green” cleaners have become increasingly popular, with an implicit assumption that these are better for our health and/or the environment.

2. Materials and Methods 2.1. Sunscreen Selection Process Twenty-six sunscreen products from fifteen different brands were purchased from a major UK supermarket retailer. They were selected so that a range of different formulations and SPF ratings could be represented (Figure 1), including some products that were marketed specifically for use on the face (12 products) or for children (4 products).
