電気メッキ生産を伴う工業用作業場内の空気の状態を総合的に解析した。電気めっきの15の主要工程について、浮遊粒子の粒度別定量分布(PM,PM,PM,PM,PM,PM,PM,PM,PM)のデータを提示した。粒子表面の形態学的及び化学組成を調べた。丸みを帯びた形状の粒子、複雑な幾何学的形状を持つ様々な凝集体、吸入すると人間の健康への最大の脅威となる鋭角粒子を観察した。これらの粒子の化学分析では、非鉄金属の酸化物が絶対的に優勢であり、その割合は電気めっき浴の種類によって異なることが示された。また、各試料中の第1級(Zn, Pb, Cd)および第2級(Cu, Cr, Ni, Co, Mo)の高危険物質の含有量を記録した。

A comprehensive analysis of the state of air inside an industrial workshop with electroplating production was carried out. The data of quantitative distribution of suspended particles by size fractions (PM, PM, PM, PM, PM, PM) are presented for 15 main processes of electroplating. Morphometric and chemical composition of the surface of particles were studied. We observed particles of rounded shape, various agglomerates with complex geometric shapes, acute-angular particles, which when inhaled pose a maximum threat to human health. Chemical analysis of these particles showed an absolute predominance of oxides of non-ferrous metals, the percentage of which varied depending on the type of electroplating bath. The content of highly hazardous substances of the 1st (Zn, Pb, and Cd) and the 2nd (Cu, Cr, Ni, Co, and Mo) hazard classes in each sample was recorded.
