Styrene ranking upgraded to 'probably carcinogenic'
Styrene, a key component for many plastics and synthetic rubber, is 'probably carcinogenic to humans', according to the International Agency for Research on Cancer (IARC). An assessment this year by an IARC expert working group said there was now sufficient evidence to change its cancer rating from group 2B – 'possibly carcinogenic to humans' – to 2A, a probable cause of cancer in humans. Globally, manufacturers produce about 20m tonnes of styrene per year, according to the International Styrene Industry Forum (ISIF). This is used primarily as a monomer in the production of plastics, particularly polystyrene, which accounts for about half of global production. The evidence from human studies – which focused on workers making reinforced plastics – was 'limited', said IARC's monograph working group, in a summary paper published in The Lancet Oncology. The studies did provide "credible evidence that exposure to styrene causes lymphohaematopoietic malignancies", but there was no way to rule out "confounding, bias or chance." Animal studies provided "sufficient" evidence of a cancer association. Professor Henrik Kolstad of Aarhus University in Denmark, a member of the IARC working group, said: "The most recent styrene study shows the risk of acute myeloid leukaemia, a rare form of leukaemia, is doubled. Out of the more than 70,000 people included in the research project, we found 25 cases of acute myeloid leukaemia, where you would statistically expect to find 10. Research also found a five-fold increase in the risk of sinonasal adenocarcinoma – nasal cancer – among those who are exposed to styrene in the plastic industry."

02. pacote destaca 5 pontos para a segurança de motoristas de ônibus.
Five point safety package for bus drivers
The Queensland Government has announced it will roll out a five-point safety package for bus drivers across the state. The package includes grants for driver safety barriers and will tackle violence against bus drivers. The package is released as part of its final response to the Bus Driver Safety Review.
The plan will provide:
Physical safety measures – $3.93m for protective driver safety barriers to be installed in buses, $1.54m for anti-shatter window film installation on all Queensland buses, and reinforce contractual requirements for operators to provide onboard CCTV, duress and radio systems;
Targeting high-risk areas and building a safety culture – consistent and simplified incident reporting in order to ensure resources aimed at improving driver safety are deployed where they are most needed;
Policy and procedure changes – Introduce a Code of Conduct for Passengers, improve incident reporting procedures and provide customer service cards to drivers to assist with de-escalation of potential incidents;
Education and increased safety awareness – develop a public awareness campaign promoting safe travel behaviours and expand the Step Up school safety education program; and
Sharing best industry practice – De-escalation training, recruitment and training processes, and fare evasion awareness.
