“…In an earlier study, we reported poor general and respiratory health among ragpickers in India 5) . We found a marked reduction in lung function in a large majority of ragpickers, and a substantial number of them had airway obstruction with reduced forced expiratory volume in one second (FEV 1 ) and its ratio with respect to forced vital capacity (FVC; FEV 1 /FVC), suggesting the possibility of airway inflammation.…”

Over one million ragpickers collect and sale recyclable materials from municipal solid wastes (MSW) in India for a living. Since MSW contains a host of pathogenic microorganisms, we investigated the occurrence of airway inflammation and its underlying mechanism in 52 non-smoking female ragpickers (median age 29 yr) and 42 control women matched for age, smoking habit and socioeconomic conditions in Kolkata, eastern India. Methods: Spontaneously expectorated sputum were stained using the Papanicolau method for cytology, and flow cytometry was used for measurements of surface expression of β 2 Mac-1 integrin (CD11b/CD18) on leukocytes and P-selectin on platelets. The concentrations of pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-α) and chemokine interleukin-8 (IL-8) were measured in plasma by enzyme-linked immunosorbent assay. Results: Compared with controls, sputum samples of ragpickers contained significantly increased numbers of alveolar macrophages, neutrophils, eosinophils and lymphocytes, suggesting airway inflammation. Circulating neutrophils and monocytes of the ragpickers overexpressed CD11b/CD18 and their platelets had upregulated surface expression of P-selectin, implying functional activation of these cells. In addition, plasma levels of IL-8 and TNF-α were significantly increased, indicating greater trafficking of leukocytes from circulation to the tissues. Multivariate logistic regression analysis demonstrated a positive association between the ragpicking profession and leukocyte activation after controlling for potential confounders. Conclusions: Ragpickers experience leukocyte and platelet activation and airway inflammation that could make them more vulnerable to tissue damage and cardiovascular diseases.

“…Two studies 19,20 found waste pickers to be exposed to high levels of ambient air pollutants including PM, NO 2, and heavy metals. Three studies 17,18,20 reported high occurrence of respiratory symptoms, skin allergies, asthma, and injuries among waste pickers. Impaired lung function among waste pickers was noted by two studies.…”

“…Impaired lung function among waste pickers was noted by two studies. 18,19 Waste pickers also inhale methane, hydrogen sulfide, and other noxious gases generated from decomposing waste materials. At the same time, waste pickers often do not wear personal protective equipment and frequently use their bare hands and feet for scavenging.…”

“…13,14 Exposure experiences of waste pickers and associated adverse health outcomes A systematic search of PubMed and Scopus databases identified six studies [15][16][17][18][19][20] that provide evidence of the environmental exposures and associated common illnesses of waste pickers (Table 2). Four studies [15][16][17][18] found waste pickers to be exposed to several pathogens including Hepatitis A virus, Toxoplasma gondii, Bacillus spp., Clostridium spp., Enterobacter spp., and Escherichia coli. Two studies 19,20 found waste pickers to be exposed to high levels of ambient air pollutants including PM, NO 2, and heavy metals.…”

Uncontrolled urbanization in developing countries has led to widespread urban poverty and increased susceptibility to environmental exposures owing to the hazardous occupational activities of the urban poor. Street vending and waste picking are the dominant works undertaken by the urban poor, and besides the physical hazards, it also exposes them to several pathogens and high levels of air pollutants present in the outdoor environment. The situation has severe consequences for the health of the workers. Eliminating these occupational activities from the urban landscape of developing countries should therefore receive urgent attention from the global health community and governments. In this article, we provide evidence to support this policy recommendation by documenting exposure experiences of the workers, the associated adverse health effects, whilst also outlining measures for addressing the problem sustainably. We conclude that with the adoption of the sustainable development goals (SDG), governments now have a commitment to address poverty and the associated occupational health hazards experienced by the poor through their choices to help achieve the health-related SDG target (3.9) of substantially reducing the number of deaths and illnesses from hazardous chemicals and air, water, and soil pollution and contamination by 2030.

“…A study at the Jatibarang Landfill, Semarang-Indonesia reported the incidence of chest pain, respiration, headache, coughing and breathing pattern shortness as the impacts of excessive inhalation of ammonia gases (NH3) and Hydrogen Sulphide (H2S) [3]. In addition, the respiratory infection was also found among the waste pickers in Delhi, India suffered from respiratory infection, increasing the inflammatory of cell in sputum and peripheral blood leucocytosis [12]. Dermatological issues are also emerging among the waste pickers.…”

<span lang="EN-US">Waste pickers are those who collect, sort and sell recyclable waste for a living. Waste pickers are vulnerable to various health problems, particularly high risk of occupational health. This study intended to overview the capability of the waste picker to manage the emergency care due to their unsafe working condition. It is a descriptive study involving 48 waste pickers. The study revealed the poor knowledge and practices of the waste pickers in handling their emergency care. Therefore, it exacerbates their health and become riskier to diseases and illness. Improving the knowledge of the waste pickers regarding the emergency care and the provision of health programs accommodating the waste pickers is necessary.</span>
