Objectives Following an earthquake that occurred in middle Italy in 2009, the involved territory hosted in 10 years thousands of construction sites. The aim of this study is to assess inhalable, respirable, and respirable crystalline silica exposure of the construction workers involved in the rebuilding activities. Methods Six construction companies joined the study and hosted the air sampling activities. We identified four work tasks: bricklayer and similar; scaffolder and carpenter; manual demolition; other tasks. We reported 8‐h time‐weighted concentrations. Results The “All tasks” geometric mean concentration of inhalable dust was 4.73 mg/m 3 and the higher, TLV exceeding exposure was observed for “Manual demolition workers” (13.92 mg/m 3 , GM). The “All tasks” geometric mean concentration of respirable dust was 0.25 mg/m 3 and no TLV‐exceeding exposure (geometric mean values) was observed among the work‐related groups. About the respirable crystalline silica dust exposure, the “All tasks” average concentration was 0.004 mg/m 3 . No TLV‐exceeding exposure was observed among the whole data sample. Conclusions The comparison of the results shows that manual demolition workers are exposed to high levels of inhalable dust, exceeding the TLV‐TWA (Threshold Limit Values‐Time Weighted Average) limit of 10 mg/m 3 . About the respirable dust concentration, none of the analyzed work task dust concentrations exceeded the TLV‐TWA limit of 3 mg/m 3 (geometric mean values). Measurements of respirable crystalline silica dust have shown levels below the threshold limit value of 0.025 mg/m 3 . Our findings overall match with the available scientific data.

The aim of the present study was to evaluate the contamination levels of some classes of persistent organic pollutants (POPs) in free-range hen eggs and to estimate the related human dietary exposure in a Site of National Interest (SNI), characterized by a serious state of environmental pollution (Bussi sul Tirino area, central Italy). For these purposes, 17 samples of free-range hen eggs collected in home-producing farms located in the SNI territory were analyzed for 17 polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), 12 dioxin-like polychlorinated biphenyls (dl-PCBs) and 6 non-dioxin-like PCBs (ndl-PCBs). Dietary exposure was assessed assuming a standard consumption of eggs per week. The concentration of ∑PCDD/Fs + dl-PCBs ranged from 0.463 to 8.028 pg TEQ (Toxic Equivalent) g−1 fat, while the mean contamination level of the ∑ndl-PCBs ranged from 0.234 to 7.741 ng TEQ g−1 fat. PCDD/Fs and PCBs contamination levels were lower than maximum values established by the Commission Regulation (EU) 1259/2011, except for one sample. The estimated weekly intake (EWI), calculated in order to evaluate the contribution in terms of the monitored pollutants of the locally produced eggs to the diet, was lower than the tolerable weekly intake (TWI) established by the European Food Safety Authority (EFSA).
