[Association between occupational exposure to pesticides and ototoxicity in farmers of Pontal do Paranapanema-SP, Brazil].

The scope of this study was to assess the ototoxic effects and general health of farmers exposed to pesticides in the Pontal do Paranapanema region, SP, Brazil. Participants of both sexes aged 18-40, 40-60 and >60 years were allocated into two groups: Non-Exposed Group (NEG) and Occupationally Exposed Group (OEG). A questionnaire of exposure and health, meatoscopy, pure tone audiometry, logoaudiometry and immittanciometry were assessed.

Lost life expectancy following a hypothetical urban radiological incident.

The consequences of mass radiological events, particularly those involving the activation of a radiological dispersion device (RDD), have been extensively studied by scientific groups. However, the critical initial period of such an event, usually spanning the first 100 h, can be characterized by a scarcity of information, potentially leading to delays in mitigating strategies. In response, a research group utilized computer simulations to generate solid, conservative analytical details that can aid decision-making and guide the prioritization of initial care based on variables such as age, sex, location, and local atmospheric stability conditions.

'Glocalizing' land-use and forest governance in the tropics: examining research partnerships and international forest policies affecting Brazil, DRC and Indonesia.

International and market forces are key drivers of deforestation and forest degradation, with transnational and market-based solutions in land-use and forest governance often missing economic, distributive, and environmental targets. This paper tackles both the framing and effectiveness of transnational initiatives affecting forest lands and peoples in the Global South, and the quality of relationships between institutions in the Global North and the Global South. Through more equitable research partnerships, this paper draws lessons from case studies in Indonesia (legality verification system in different forest property regimes), the Democratic Republic of the Congo (lifting of a moratorium on new logging concession), and Brazil (FSC in the Amazon region and the Amazon Fund).

Digital image processing: a useful tool in the analysis of lung injuries caused by chronic inhalation of agricultural herbicides.

The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) is widely used in agriculture to control various weeds. The objective of this study was to use the digital image processing method to identify alveolar lesions in the lungs of rats submitted to chronic 2,4-dichlorophenoxyacetic acid (2,4-D) inhalation exposure. We used forty adult male Wistar rats.

Maternal and developmental toxicity after exposure to formulation of chlorothalonil and thiophanate-methyl during organogenesis in rats.

Chlorothalonil and thiophanate-methyl are fungicides widely used in agriculture. The aim of this study was to assess maternal toxicity and embryotoxic potential of exposure to chlorothalonil and thiophanate-methyl during organogenesis period in rats. Pregnant rats were divided into four groups: control and exposed to 400 (CT400), 800 (CT800) and 1200 mg-1kg bw-1 day (CT1200) of commercial formulation constituted of 200 g of thiophanate-methyl kg-1 and 500 g of chlorothalonil kg-1 by gavage, from 6th to 15th gestational day.
