In Europe sulfur dioxide (SO2) and sulfites in foods and beverages at concentrations of more than 10 mg kg-1 or 10 mg L-1 expressed as SO2 equivalents are subject to mandatory labelling. In fresh meats the addition of sulfites is not admitted because of their unlawful use to give the product a more attractive appearance. Aim of the study was to detect sulfites in meat product sampled in 19 comm...

It is generally assumed that limestone absorbs SO2 by a mechanism involving two consecutive steps, dissociation of the calcium carbonate followed by reaction of C.0 with sulfur dioxide. be important in any of the proposed pollution control processes. and especially in the dry injection process (Potter, 1968). Several investigators (Harrington, 1968, Potter, 1969) have determined the saturation ...

A Pt microelectrode modified with nickel(II) polytetramethyldibenzo[b,i]tetraaza[14]annulene was prepared by electropolymerization of nickel(II) tetramethyldibenzo[b,i]tetraaza[14]annulene monomers and applied to determine sulfur dioxide in vitriol plant wastewater. For determination of SO2 with this electrochemically modified Pt microelectrode, the linear range was from 9.6 x 10(-6) to 2.4 x 1...

This paper examines the impact of various nitrogen oxides (NOx) and sulfur dioxide (SO2) emission control scenarios on the projected prices of electricity in the state of Indiana. The scenarios represent different methods for achieving the reductions in NOx and SO2 emissions mandated by the United States Environmental Protection Agency (EPA) under its Clean Air Interstate Rule (CAIR). The analy...

BACKGROUND There is growing evidence suggesting an association between air pollution and suicide. However, previous findings varied depending on the type of air pollutant and study location. OBJECTIVES We examined the association between air pollutants and suicide in 10 large cities in South Korea, Japan, and Taiwan. METHODS We used a two-stage meta-analysis. First, we conducted a time-stra...

This study focuses on determining the variation of indoor pollutants in public transport buses in the City of Toledo running on biodiesel (BD) and ultra low sulfur diesel (ULSD). The indoor pollutants monitored are carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), nitric oxide (NO), and particulate matter (PM). Temperature (Temp.) and relative humidity (RH) are also measured ins...

BACKGROUND This study investigates the effects and mechanism of sulfur dioxide (SO2) inhalation and exercise on rat myocardial collagen fiber. MATERIAL AND METHODS The rats were randomly divided into 4 groups: a control group (RG), an exercise group (EG), an SO2 pollution group (SRG), and an SO2 pollution and exercise group (SEG). Body weight, cardiac index, and left ventricular index in each g...

OBJECTIVE To analyze the air quality in elementary schools and their structural and functional conditions. METHODS Air quality in 51 elementary schools (81 classrooms) in the city of Coimbra, Portugal, both inside and outside of the rooms was evaluated during the four seasons, from 2010 to 2011. Temperature (T°), relative humidity (Hr), concentrations of carbon monoxide (CO), carbon dioxide (...

The aim of the study was to investigate the role of endogenous sulfur dioxide (SO2)/ aspartate aminotransferase 1 (AAT1) pathway in stretch-induced excessive collagen expression and its mechanism. The mechanical stretch downregulated SO2/AAT1 pathway and increased collagen I and III protein expression. Importantly, AAT1 overexpression blocked the increase in collagen I and III expression, trans...
