Đa số chất trong danh sách là hóa chất thông dụng như chloroform, formaldehyde, polychlorinated biphenyls….

Theo bà Elizabeth Ward, giám đốc nghiên cứu giám sát của hội Ung thư Mỹ, các chất trên được cho là nhân tố có thể gây ung thư do có chứng cứ cho thấy chúng có liên hệ với căn bệnh này. Bên cạnh đó, nhiều chất được sử dụng rộng rãi trong các ngành công nghiệp có nhiều người mắc bệnh cũng được đưa vào danh sách. Bà Ward cho biết lao động tại các xưởng lắp ráp và tái chế tivi có có nguy cơ nhiễm bệnh nhiều nhất.

Hóa chất mới được sử dụng nhiều trong sản xuất nhưng chưa được nghiên cứu đầy đủ cũng không được bỏ qua, trong đó có indium phosphide, một hợp chất tương đối mới dùng trong sản xuất tivi màn hình phẳng.

Cơ quan Nghiên cứu ung thư quốc tế (IARC) và cơ quan Ung thư Liên Hiệp Quốc cũng xếp 19 chất trên vào danh mục chất có khả năng gây ung thư.

Ngoài ra, làm việc đêm cũng được cho là nguyên nhân gây ung thư.

Ung thư là căn bệnh thứ hai gây nhiều người chết nhất ở Mỹ và châu Âu sau các bệnh về tim.

Danh sách 19 chất có khả năng gây ung thư:

- Chì và các hợp chất chì
- Indium phosphide: dùng trong ngành điện tử
- Cobalt với cacbua vonfram: chế tạo kim loại nặng
- Titanium dioxide: trong ngành mỹ phẩm
- Khói hàn
- Sợi gốm chịu nhiệt
- Khí thải Diesel
- Carbon đen: trong ngành chế tạo mực viết
- Styrene-7 ,8-oxide và styrene: trong khói thuốc lá, gỗ
- Propylene oxide: chế tạo chất dẻo, gây tổn hại ADN
- Formaldehyde: tăng tỷ lệ mắc ung thư máu
- Acetaldehyde: một dạng dung môi

- Dichloromethane, methylene chloride (DCM): dung môi
được dùng để tẩy sơn, chất nhờn
- Trichloroethylene (TCE): dùng để tẩy nhờn kim loại
- Tetrachloroethylene (perc, tetra, PCE): hóa chất làm sạch
- Cloroform: trong nước uống được khử trùng bằng clor
- Polychlorinated biphenyls (PCBs): hóa chất làm ô nhiễm không khí
- Di (2-ethylhexyl) phthalate (DEHP): dùng trong các sản phẩm nhựa vinyl và mỹ phẩm
- Atrazine: hóa chất diệt cỏ

Regulating the concentration of disinfecting agent during rinsing

The laundry industry is benefiting from new findings on need-based disinfecting

BÖNNIGHEIM, (im/ri) A joint research project by the Hohenstein Institute in Bönnigheim and the ITCF Denkendorf (IGF No. 15482 N), financed by the AiF with funding from the Federal Ministry of Economics and Technology, is for the first time delivering data about how best to regulate the concentration of disinfecting agent in rinsing water. Implementing the results of the research will mean that the dosage can match the need and the service life of textiles being processed can be increased, resulting in both economic and ecological improvements in the laundry sector. The washing machine and detergent industries now have the opportunity to go on to develop innovative systems for analysis and regulation. It will also be possible for companies to set up their own online system for measuring active oxygen for relatively little expense. A system of data recording enables the levels of hygiene that have been achieved during the rinsing process to be documented.

Textiles used in areas where hygiene is a high priority, notably hospital laundry or linen from food processing enterprises, must be sterile or almost sterile. Textiles are guaranteed sterile after the washing process by the legal requirements for disinfectant treatments. However, during the subsequent rinsing process, it must always be expected that bacteria may enter from the environment, so for safety reasons more disinfecting agent must be added at this stage.

To ensure that the disinfectant in the rinsing water meets the need, the researchers used an appropriate method of online analysis to calculate the effective concentration of disinfecting agent and keep it constant by continuous readjustment. As well as developing a method for determining the level of disinfecting agent in the rinsing water, and a control system that allowed the level of disinfecting agent to be adjusted, the researchers also designed an entirely new and reliable method for quickly determining the level of active oxygen, as an indication of the concentration of peracetic acid, and this was tested for its suitability for use in practice.

The online titration that they developed, like manual offline titration, is extremely accurate and linear. It is not generally sensitive to temperature variations, fluctuations in pH value or the washing agents that are added. At the same time, it is reproducible, and the progression is linear.

New protective treatment for light-coloured furnishing fabrics

BÖNNIGHEIM (ri) Furniture with light-coloured upholstery is very fashionable just now, but it gives rise to numerous complaints to retailers and manufacturers on account of discoloration caused by other textiles. Traditional stain-repellent treatments, usually based on fluorocarbon resins, are not the answer here: while they may offer effective protection from standard water- or oil-based stains such as food and drink, they cannot prevent colour transfer caused by (excess) dye in clothing or other domestic textiles.

That is why, at the Hohenstein Clothing Physiology Institute (BPI), in partnership with the German Textile Research Centre North-West, and as part of a research project (IGF no. 15151 N), they have been looking for ways of preventing light-coloured furnishing fabrics from becoming discoloured by textiles where the colourfastness is poor when rubbed.

The scientists tested to what extent an anti-adhesive, quasi-ceramic, nanosol-based coating could prevent the discoloration or at least make it easier to remove with normal cleaning methods.

As part of the project, all kinds of different nanosols were synthesised and applied to a range of furnishing fabrics. Then the textile and performance-related characteristics of materials treated in this way were analysed in detail. The results obtained show that the colour transfer is primarily caused by dye abrasion and not, as was originally thought, by abrasion of coloured fibres. It also became clear that discoloration of light furnishing fabrics could not be entirely prevented even with this approach. However, some of the synthesised treatments tested in the research project do allow the dye to be completely cleaned off by using a microfibre cloth soaked in washing solvent.

More research work will be required before the process is ready to be brought to market, because the treatments tested so far cannot yet combine complete removal of the dye with water- and oil-repellent qualities. Nevertheless, combining a number of new developments resulting from the research project may make it possible to synthesise a hydro- and oleophobic treatment which has excellent dye removing properties in the future.

We are grateful for the sponsorship for this project from the Textile Research Council, as part of the programme to support "Industrial Community Research" (IGF), with funds from the Federal Ministry of Economics and Technology (BMWi) provided through the Federation of Industrial Research Associations (AIF).
