Abstract-The accumulation of four polycyclic aromatic hydrocarbons ([PAHs]; phenanthrene, pyrene, fluoranthene, and benzo[a]pyrene) was tested in the earthworm Eisenia andrei in a spiked artificial soil medium. A typical peak in the body residues was observed for all PAHs around day 7, which could not be explained from changes in the total soil concentration. It is argued that the most likely cause of this peak is a decrease in the concentration in pore water, the main bioavailable phase for earthworms. This decrease is caused by biodegradation while the low rate of mass transfer from the solid state precludes replenishment. To describe the data, bioavailability was assumed to decline exponentially in time, but the shape of the accumulation curves suggests a more abrupt change. Estimates of the uptake rate (k 1 ) are similar for all PAHs when expressed on soil solution basis (approximately 2,000 L/kg/d); the elimination rate (k 2 ) shows a decrease with K ow as expected, but the values tend to be slightly lower than literature data. The dynamic bioconcentration factors (k 1 /k 2 ) agree well with an equilibrium partitioning between soil water and the phases inside the organism.

Purpose – The purpose of this paper is to gain insight into international career motives, repatriation and career success of Indian women in Science and Technology. Design/methodology/approach – In total, 30 semi-structured interviews were conducted with (upper) middle-class Indian women in Science and Technology in Bangalore and New Delhi, India. Findings – Thematic analysis resulted in four themes – International career motives, Theme 1: cross-cultural and scientific exposure; Repatriation reasons and experiences, Theme 2: family reunion, career prospects and readjustment; Career success, Theme 3: international experience; and career growth, Theme 4: social responsibility. Motives for international career mobility of Indian women were: exposure to foreign cultures, international collaboration in science and personal and professional development. Family formation and reunion and career prospects were reasons for repatriation and positively influenced repatriation experiences of Indian women. Readjustment to people and conditions in India impacted their repatriation experiences negatively. The meaning women attribute to career success is grounded in recognition from peers in science, career growth, satisfaction and contribution to science and Indian society. Research limitations/implications – The sample of Indian female scientists may limit generalization of the findings to global career professionals in other professions from other countries with different socio-cultural and economic contexts. Practical implications – HR policies that foster international careers of women scientists as well as women's networks in science to share and apply knowledge, and their contribution to the Indian economy and society will enhance global career success of women and strengthen the sustainable competitive position of organizations. Originality/value – The study provides new insights into motivation for international career mobility and repatriation of women professionals from a developing country and their career success in the home country, and contributes to the development of theoretical frameworks on international career mobility and career success.
