Abstract
Phthalates are a huge class of chemicals with a wide spectrum of industrial uses, from the manufacture of plastics to food contact applications, children's toys, and medical devices. People and animals can be exposed through different routes (i.e., ingestion, inhalation, dermal, or iatrogenic exposure), as these compounds can be easily released from plastics to water, food, soil, air, making them ubiquitous environmental contaminants. In the last decades, phthalates and their metabolites have proven to be of concern, particularly in products for pregnant women or children. Moreover, many authors reported high concentrations of phthalates in soft drinks, mineral waters, wine, oil, ready-to-eat meals, and other products, as a possible consequence of their accumulation along the food production chain and their accidental release from packaging materials. However, due to their different physical and chemical properties, phthalates do not have the same human and environmental impacts and their association to several human diseases is still under debate. In this review we provide an overview of phthalate toxicity, pointing out the health and legal issues related to their occurrence in several types of food and beverage.

Abstract
The potential chronic health risks of occupational and environmental exposure to styrene were evaluated to update health hazard and exposure information developed since the Harvard Center for Risk Analysis risk assessment for styrene was performed in 2002. The updated hazard assessment of styrene's health effects indicates human cancers and ototoxicity remain potential concerns. However, mechanistic research on mouse lung tumors demonstrates these tumors are mouse-specific and of low relevance to human cancer risk. The updated toxicity database supports toxicity reference levels of 20 ppm (equates to 400 mg urinary metabolites mandelic acid + phenylglyoxylic acid/g creatinine) for worker inhalation exposure and 3.7 ppm and 2.5 mg/kg bw/day, respectively, for general population inhalation and oral exposure. No cancer risk value estimates are proposed given the established lack of relevance of mouse lung tumors and inconsistent epidemiology evidence. The updated exposure assessment supports inhalation and ingestion routes as important. The updated risk assessment found estimated risks within acceptable ranges for all age groups of the general population and workers with occupational exposures in non-fiber-reinforced polymer composites industries and fiber-reinforced polymer composites (FRP) workers using closed-mold operations or open-mold operations with respiratory protection. Only FRP workers using open-mold operations not using respiratory protection have risk exceedances for styrene and should be considered for risk management measures. In addition, given the reported interaction of styrene exposure with noise, noise reduction to sustain levels below 85 dB(A) needs be in place.

Abstract
The immunotoxicological effects of piperine were investigated in Swiss male mice, gavaged at a dose of 1.12, 2.25 or 4.5 mg/kg body weight for five consecutive days. All the dose levels had no overt toxic effect and the liver gained weight normally. Treatment at highest dose, however, resulted in significant decrease in the weight of spleen, thymus and mesenteric lymph nodes, but not of peripheral lymph nodes. All the dose levels suppressed the cellular population of lymphoid organs, except for the spleen, where the doses of 1.12 and 2.25 caused an increase. Haematologically, doses of 2.25 and 4.5 mg/kg caused a significant reduction in total leucocyte counts and differential leucocyte counts showed an increase in the percentage of neutrophils. The higher doses of 2.25 and 4.5 mg/kg suppressed the mitogenic response of B-lymphocyte to lipopolysaccharide. The number of primary antibody (IgM) forming cells in the spleen and the level of primary antibody in serum, was decreased. The doses of 1.12 and 2.25 mg/kg suppressed the mitogenic response of T-lymphocytes to phytohaemagglutinin and the nitroblue tetrazolium (NBT) dye reducing activity of peritoneal exudate cells (PECs). Since the lowest dose of 1.12 mg of piperine per kg body weight had no immunotoxic effect, it may be considered as immunologically safe "no observed adverse effect level (NOAEL)" dose.

Abstract
OBJECTIVES To clarify whether di (2-ethylhexyl) phthalate (DEHP) has immunotoxic effects on both the expression of surface molecules (CD3, CD4, CD8 and CD28) on T cells of the thymus and spleen in male C57BL/6 mice. METHODS Animals were orally administered a 0.1% or 0.2% DEHP-containing diet for 10 or 20 days. Dietary corn oil was used as the vehicle for DEHP in preparing the diet. RESULTS Significant hepatic hypertrophy was clearly observed in the DEHP-exposed groups, while no atrophy was seen in the thymus or spleen in any treatment groups. In the thymus and spleen, no variation in the proportions of both T cells expressing CD3, CD4 and CD8 was shown with cytometry analysis. The surface expression of CD3, CD4, CD8 and CD28 on both T cells was also invariable in all analyzed stages of thymic differentiation and in the spleen. No effect of DEHP on mitogenesis was shown in the splenic T cells with anin vitro [(3)H]-thymidine-incorporation technique. CONCLUSIONS DEHP is probably not an immunosuppressor, particularly for T cells.

Abstract
Styrene is an indispensable chemical extensively used in plastic and synthetic rubber industries. Styrene is known to produce various types of hepatotoxic, neurotoxic, and genotoxic effects. Styrene may be immunotoxic by both direct and indirect mechanisms. Measurement of adhesion molecules is a new tool for the investigation of immune system modulation. The aim of this study was to evaluate the association of the expression of the adhesion molecules CD11a, CD11b, CD18, CD54, CD49d, and CD62-L in white blood cells and levels of soluble adhesion molecules ICAM-1 and L-selectin in serum with occupational exposure to styrene. Analyses by flow cytometry revealed elevated levels of most of the assessed adhesion molecules on surfaces of lymphocytes, monocytes, and granulocytes. Expression of the adhesion receptor antigens CD11a on lymphocytes, CD11b on monocytes, and CD18 on granulocytes were unaffected. Workers exposed to styrene had decreased concentrations of sICAM-1 and no changes in concentrations of sL-selectin. Styrene exposure appears to increase activation of the immune system and alter leukocyte adherence. This interaction is a critical first step in immune stimulation and leukocyte-endothelial interaction.

Abstract
A comprehensive approach to biological monitoring of 44 workers occupationally exposed to styrene in a hand lamination plant was performed by using several end-points: styrene in workplace air, styrene in exhaled air, styrene in blood, DNA strand breaks (SBs) and oxidised bases in mononuclear leukocytes, chromosomal aberrations in lymphocytes, immune parameters and genotyping of polymorphic genes of some xenobiotic-metabolizing enzymes (CYP 1A1, EPHX, GSTM1 and GSTP1). We found a significantly higher number of DNA SBs, measured by a modified comet assay, in mononuclear leukocytes of the styrene-exposed workers compared with results from 19 unexposed controls (P<0.001). A fairly strong correlation was observed between SBs and years of exposure (P<0.001, r=0.545). The styrene-exposed workers also showed a significantly increased frequency of chromosomal aberrations (P<0.0001 for highly exposed group, P<0.004 for medium-exposed group, and P=0.0001 for low-exposed group). The proliferative response of T-lymphocytes stimulated with concanavalin A was significantly suppressed in people exposed to styrene (P<0.05). We recorded a significant increase of the percentage of monocytes in differential white blood cell counts in the exposed group (P<0.05). Using flow cytometry, we found an increased expression of adhesion molecules CD62L, CD18, CD11a, CD11b, CD49d and CD54 in the exposed workers as compared with the control group (P<0.05).

Abstract
This review article considers evidence regarding the toxicological impact of new carpet emissions on indoor air quality and human health. It compares emissions data from several studies and describes the dominant compounds found in those emissions. The toxicity of each these compounds is assessed for animal and human data, with a focus on inhalation exposure. Data for acute and chronic exposures are presented, and synergistic effects are considered. Differences and similarities between health responses caused by toxicity and/or by immunological reactions are discussed. Possible neurogenic pathways and associations between these and immune changes are considered as they might relate to inflammatory-based human reactions. Additionally, factors affecting human odor responses are described. The roles that a variety of psychological factors may also play in the etiology of potentially related phenomena, such as the sick building syndrome, pathogenic illness, and multiple chemical sensitivity, are considered. Gaps in the literature are identified within the article and suggestions for future research are offered. In particular, it is noted that few, if any, prior studies have evaluated both neurogenic and immune-mediated inflammation status within the same study. Based on the present information available, it is concluded that under normal environmental circumstances, VOC emissions from new carpets are sufficiently low such that they should not adversely affect indoor air quality or pose significant health risk to people.
