“…This indicates that roofing materials can be an important long-term source of As, Cu, and Zn in stormwater runoff. This result correlates with [68]. In the same study, [67] observed a much lower release of Zn from painted galvanized steel than from Zincalume ® , which demonstrates the importance of coating for reducing metal emissions from metal roofing materials.…”

Green roofs (GRs) and vertical greenery systems (VGSs) can contribute certain pollutants to stormwater runoff, affecting the quality of the receiving waters. The objective of this review paper is to discuss the potential impact of these systems on the quality of urban runoff. In the green building systems section, a series of materials used in greenery systems and their specific application are presented and environmentally relevant substances that could be leached out from these materials are identified as potential pollutants. After the identification of environmentally relevant pollutants that have already been measured in urban runoff and originate from these systems, an assessment of their pathways, fate, and impact in the aquatic environment is performed. Since GRs and VGSs are already considered to be solutions for stormwater quantity and quality management in urban areas, recommendations for mitigating their environmental impact through runoff are needed. It can be concluded that special focus should be placed on measures that target the pollution source, such as optimizing GR and VGS construction practices and materials used, as well as establishing appropriate decentralized stormwater treatment measures. Both of these approaches will help to reduce or even entirely avoid the emission of relevant pollutants into the aquatic environment.

“…These, as well as concrete and asphalt products, have the potential to release metals into urban stormwater runoff. Research on this topic has been widely documented and several studies have already confirmed severe metal contamination in runoff from metallic or partly metallic roofs and facades [35,63,64].…”

“…Heavy metal contamination in stormwater runoff can result in both acute and chronic impairment of receiving water bodies. Similar to sediment research, the studies investigating heavy metals focused on build-up and washoff from roofs (Winters et al, 2015;Yu et al, 2015) and road surfaces (Gunawardena et al, 2015;Murphy et al, 2015a, b year of installation. Metals concentration in roof runoff from this study was also affected by climatic conditions.…”

The following review presents a synthesis of 181 journal articles published during 2015 that represent progress toward better characterizing, controlling, and treating urban stormwater runoff. The review is structured by general topical areas related to (1) stormwater quality and quantity characterization; (2) engineered stormwater control and treatment practices, including erosion and sediment control, stormwater ponds, constructed stormwater wetlands, bioretention, permeable pavement, greenroofs, and rainwater harvesting systems; and (3) watershed-scale modeling and optimization of stormwater control and treatment practices. Common research themes emerging from this collection of studies include potential to enhance hydrologic and pollutant treatment performance of stormwater practices via media amendments and the use of innovative outlet control structures, as well as development of a more mechanistic understanding of hydrologic and water-quality functions to inform modeling and performance predictions. These studies serve to expand the field's knowledge base and will inform future efforts to further improve stormwater control and treatment at various spatial and temporal scales.

RESUMO As telhas de aço usadas em galpões de fazendas expostas às intempéries ficam vulneráveis à degradação. A corrosão surge devido à diferença de potencial elétrico entre a superfície metálica e o meio, levando a um carregamento elétrico dessa superfície. Elas então necessitam da proteção de um recobrimento anticorrosivo, cujo objetivo é aumentar sua vida útil. Atualmente um recobrimento usado para diminuir os efeitos do sol e da chuva em telhas metálicas é o de zincalume, que consiste em uma liga de zinco e alumínio. Este recobrimento permite a combinação do zinco com alumínio, que alia a resistência por barreira do primeiro ao bom desempenho do segundo em proteger bordas e pequenas descontinuidades. Este produto mantém a força estrutural do aço-base e confere alta resistência à corrosão atmosférica, interrompendo a corrente elétrica. Neste trabalho foi analisada a degradação das telhas de aço recobertas com uma camada de zincalume sujeita à ação do tempo. Análises com fluorescência de raios X foram utilizadas a fim de se verificar a composição química das amostras estudadas. Foram realizadas também análises macrográficas e micrográficas, a fim de se avaliar a degradação das telhas.
