Owing to the extensive use of artificial turfs worldwide, over the past 10 years there has been much discussion about the possible health and environmental problems originating from styrene-butadiene recycled rubber. In this paper, the authors performed a Tier 2 environmental-sanitary risk analysis on five artificial turf sports fields located in the city of Turin (Italy) with the aid of RISC4 software. Two receptors (adult player and child player) and three routes of exposure (direct contact with crumb rubber, contact with rainwater soaking the rubber mat, inhalation of dusts and gases from the artificial turf fields) were considered in the conceptual model. For all the fields and for all the routes, the cumulative carcinogenic risk proved to be lower than 10(-6) and the cumulative non-carcinogenic risk lower than 1. The outdoor inhalation of dusts and gases was the main route of exposure for both carcinogenic and non-carcinogenic substances. The results given by the inhalation pathway were compared with those of a risk assessment carried out on citizens breathing gases and dusts from traffic emissions every day in Turin. For both classes of substances and for both receptors, the inhalation of atmospheric dusts and gases from vehicular traffic gave risk values of one order of magnitude higher than those due to playing soccer on an artificial field.
由于全球范围内广泛使用人造草皮，过去 10 年来，人们一直在讨论源自苯乙烯-丁二烯再生橡胶的可能存在的健康和环境问题。在本文中，作者借助 RISC4 软件，对意大利都灵市的五个人造草皮运动场进行了二级环境-卫生风险分析。在概念模型中考虑了两个受体（成年运动员和儿童运动员）和三种暴露途径（直接接触碎屑橡胶、接触浸泡橡胶垫的雨水、吸入人造草皮场地的粉尘和气体）。对于所有场地和所有途径，累积致癌风险均低于 10(-6)，累积非致癌风险低于 1。户外吸入粉尘和气体是致癌和非致癌物质的主要暴露途径。吸入途径得出的结果与在都灵市每天因交通排放而吸入气体和粉尘的市民进行的风险评估结果进行了比较。对于这两类物质和两个受体，车辆大气粉尘和气体的吸入所带来的风险值比在人造草地上踢足球的风险值高出一个数量级。
