IICRC S520 Standard & Reference Guide for Professional Mould Remediation

The World Health Organization (WHO) has released Guidelines for Indoor Air Quality: Dampness and Mould. This document provides a comprehensive review of the scientific evidence on  health problems associated with building moisture and biological agents. The review concludes that the most important effects are increased prevalences of respiratory symptoms, allergies and asthma as well as  perturbation of the immunological system. The document also summarizes the available information on the conditions that determine the presence of mould and measures to control their growth indoors. WHO  Guidelines for protecting public health are formulated on the basis of the review.
